This Is What Might Happen if an Asteroid Crashed Into Your Town

An online simulator lets you launch an asteroid at a locale of your choosing and ponder the potential outcome.

If an asteroid made of pure gold, with a diameter of 2,600 feet and blasting at 77,000 miles per hour, came in at an angle of 48 degrees and hit New York City’s Upper East Side, aka around where I live, I unfortunately now know what would happen.

Myself and 6,363,353 people would be vaporized within the space rock’s resulting crater, a massive chasm over half a mile deep. The shard would release more energy than the last volcanic eruption of Yellowstone, a colossal disaster that, thousands of years ago, spewed ash, magma and debris far enough to cover most of the continental United States.

Or at least that’s what I learned from an asteroid simulation website this afternoon while sipping on a cup of coffee.

The Asteroid Launcher is a free, data-driven concept created by Neal Agarwal, a developer widely known by his online persona: neal.fun. Agarwal’s goal is basically to blend immense arrays of data and interesting mental dilemmas to form clever, interactive online thought experiments, like this one that tells you what kind of devastation would follow an asteroid smashing into your town.

«The main inspiration,» Agarwal told me over email, «was definitely growing up watching movies like Deep Impact and Armageddon! I’ve always wanted to have an online tool that would let me test out different impact scenarios and see the effects.»

But of course, the key here with Asteroid Launcher lies in Agarwal’s pseudonym.

There are thankfully no known significant impact threats for the next hundred years or more, according to NASA — and, worst case, the agency is well on its way toward generating a sort of asteroid defense system with the resounding success of its DART mission, which took place earlier this year.

Still, it doesn’t hurt to cater to our intrusive thoughts once in a while. Just for fun.

Peruse Agarwal’s projects and you’ll find an awesome array of rabbit holes to get lost in.

The Size of Space progressively presents you with larger and larger objects, starting with an astronaut and making its way through stars so enormous they make our sun look like a feeble yellow pom-pom. Spend Bill Gates’ Money offers you $100 billion to spend on items ranging from a 12 pack of Coca-Cola all the way to a literal Boeing 747 commercial airplane. It shows you how much money multibillionaires are working with day to day.

And my personal favorite, Absurd Trolley Problems takes you on an illustrative, ethical journey based on English philosopher Philippa Foot’s fictional scenario where an onlooker has the choice to save five people in danger of being hit by a trolley — except the only way to save them is by killing one person in their stead. The hard part about this isn’t so much the decisions, but the fact that you should, hypothetically, remain consistent in every one of those decisions.

«I’ve kept a big ideas list since I was 16, and have recently passed 1,000 project ideas written down (most of them terrible),» Agarwal said. «The ideas can come from everywhere, from books and movies to a conversation with a friend. I think the important thing is writing them down and being as open as possible to new and weird ideas. Sometimes two to three bad ideas can combine and form a great project.»

Which brings us to Agarwal’s latest endeavor: Asteroid Launcher.

You begin by designing your own asteroid, entering a material, rock diameter, speed and impact angle. Then, you can select any location on a realistic map to the left of the screen. All that remains, at that point, is to click a giant button that says LAUNCH ASTEROID.

Boom.

You arrive at a page that tells you, theoretically, what you’ve just done to your location of choice.

These results are surprisingly detailed, as Agarwal embedded his code with asteroid information gleaned from academic science publications, such as a doctoral thesis about asteroid impact risk and a peer-reviewed population vulnerability model authored by experts from NASA, Lancaster University and the University of Southampton.

However, it does appear that some question the results of Asteroid Launcher — one scientist, for instance, tweeted his preference for the more old-school Earth Impact Effects Program to satisfy doomsday cravings.

Though, to that end, Agarwal says the Earth Impact Effects Program uses the same equations as Asteroid Launcher because both are based on a research paper written by Gareth Collins, an asteroid impact expert at Imperial College London. «They’ll give pretty much the same results,» he explained, noting that Clemens Rumpf, an asteroid risk expert who formerly worked at NASA, also contributed to his project.

«The goal of neal.fun is to bring back the weird and fun internet!» Agarwal said. «I grew up at a time when the internet was full of strange and fun flash games and experiments, and watched that all slowly go away as social media took over. Now the web is finally becoming powerful enough again to create fun digital experiences, and I’m excited to keep exploring the potential with new projects.»

On Asteroid Launcher, once you’ve pressed the big red button, scroll down a little, and you’ll catch far more than fatalities spurred by your asteroid design.

Agarwal tells you how many gigatons of TNT your explosion equaled, how many people would receive second-degree burns if your asteroid was closer to a huge fireball, the radius within which peoples’ eardrums would rupture from the shock wave and within which homes would be completely leveled from wind speeds upon impact.

It’s darkly obsessive to check out as many asteroid designs as you can. Immediately after making my dream gold impactor, I plugged in the stats of the asteroid that NASA’s DART spacecraft punched into in an attempt to change the relatively small space rock’s orbit around a larger hunk of space rock.

I couldn’t get things to be completely accurate, because this is so theoretical, but here’s what I came up with.

Dimorphos is considered to be made of «rubble,» aka a bunch of materials, so for material, I went with generic stone. It’s actually about 525 feet in diameter, but Asteroid Launcher requires some rounding. I put in 500 feet. As for speed at time of impact, a parameter we don’t know, I popped in the speed at which the DART spacecraft hit the rock, because, well, why not? That came out to something like 14,400 miles per hour, which had to be rounded as well. I set the location to London and angle to 90 degrees for no reason whatsoever.

Here’s what we got for results — they’re much less shocking than my first ridiculous, gleaming monster asteroid.

My next plan was to input the parameters of the dinosaur-killer asteroid, Chicxulub. But get this: It was so gigantic it didn’t even fit in the diameter section.

«Asteroid impact science is still an evolving field and not everything is known yet,» Agarwal said. «Generally the larger the asteroid, the more uncertain we are about the effects.»

Nintendo Switch 2: Everything We Know About the Console, New Games, Release Date

The $450 console will get Mario Kart World at launch, 4K gaming when docked, Switch 2 Edition game enhancements and new mouse controls.

The Nintendo Switch 2 console’s biggest reveal yet arrived Wednesday morning as part of the company’s Nintendo Direct event. This teed up a day of Switch 2 reveals that include its June 5 release date, a $450 price, its specs, and its initial game lineup that extends from launch into 2026.

The console will be further buoyed by having Mario Kart World as a launch title, which will go on sale in either a $500 bundle with the Switch 2 or on its own for $80 — making the open-world racing game one of Nintendo’s most expensive yet. Other games announced, such as Donkey Kong Bananza, are being priced around $70, which matches the cost of 2023’s The Legend of Zelda: Tears of the Kingdom. That Zelda game and Breath of the Wild are among the original Switch titles that will get enhanced Nintendo Switch 2 Edition upgrades, a premium upgrade allowing players to get new features, modes and graphical enhancements that take advantage of the newer system’s capabilities.

Here are the top highlights from Nintendo’s console event, all of the games we’ve heard about so far (including new titles, Nintendo Switch 2 Edition titles and GameCube games coming to Nintendo Switch Online) and all of our coverage so far. You can also check out our Nintendo Switch 2 live blog for even more updates about the Switch 2 as we learn them.

Nintendo Switch 2 console

The Nintendo Switch 2’s specs saw a noticeable technical bump over the Switch. The Nintendo Switch 2 has a 7.9-inch, 1080p resolution LCD that supports a 120Hz refresh rate — matching what we now see on most Android phones. When the Switch 2 is docked, compatible games can run in 4K resolution. The new dock also includes a cooling fan.

The Switch 2 comes with 256GB of internal storage, and the new Switch 2 Game Cards will load games faster. For digital libraries, however, the Switch 2 will only work with microSD Express cards, which are different from the microSD cards that are compatible with the prior Nintendo Switch. Nintendo will have a Software Transfer feature available to help move games and data from the original Switch to the Switch 2.

The new Joy-Con for the controllers will support mouse controls, and a new C button will be part of a new GameChat communication feature that allows both voice and video chat. There’s also a Nintendo Switch 2 Camera, allowing players to see each other.

The Switch 2 also adds a second USB-C port to the top of the system, which Nintendo says can help connect its new camera accessory or charge the console when playing in tabletop mode. Nintendo also revealed a new Switch 2 Pro Controller with the C button and customizable GL and GR buttons on the back.

Following the presentation, Nintendo unveiled the system’s price of $450 in the US. It will also sell the Switch 2 bundled with a digital version of Mario Kart World for $500.

Mario Kart World

Mario Kart World removes its traditional boundaries and lets drivers roam freely across an entire world of race courses. The game will get its own Nintendo Direct later this month, where we’ll see additional details, but we already know it’ll include traditional races and a Free Roam mode, much like in the Forza Horizon series.

Getting the game bundled for an extra $50 on the cost of the Switch 2 might be the move if you are interested in the game, because Nintendo announced on its website that standalone copies of Mario Kart World will cost $80.

Joy-Con 2 C button and GameChat

Nintendo’s rolling out its new C button across several new Switch 2 controllers. The button will be used for the new GameChat communication features without a headset. The button will be used alongside a microphone on the console itself, which Nintendo says can be used whether it’s docked to a TV or in handheld mode.

In its teaser video, Nintendo promises the microphone will be able to cancel out loud background noises. GameChat will also work with a Nintendo Switch 2 Camera, allowing video chat and various camera-based game modes in supported titles. GameChat will be free at launch through March 31, 2026.

Nintendo Switch 2 Edition games upgrade titles

The Nintendo Switch 2 will play three types of games: original Switch games, Switch 2 games and Switch 2 Edition games that will receive substantial enhancements. For many of these Switch 2 Edition games, you’ll need to buy an upgrade pack if you own the original for Switch. Many of them will get more than just enhanced graphics in the upgrade; for example, Super Mario Party Jamboree will get new games that support the new Joy-Cons’ mouse controls, audio recognition and video camera gameplay options through the Switch 2 Camera.

Other Nintendo Switch games that are getting Switch 2 Edition options include The Legend of Zelda Breath of the Wild, The Legend of Zelda Tears of the Kingdom, Kirby and the Forgotten Land, Metroid Prime 4 Beyond and Pokemon Legends: Z-A. Enhancements vary: The Zelda games will start working with a companion phone app for maps and sending schematics to friends, while Kirby will get a new story that’s exclusive to the Switch 2 Edition. On the third-party side, Civilization 7 will get mouse controls.

Nintendo did not announce what upgrade packs will cost. However, some Switch games will get free updates that will improve performance or enhance features when playing them on the Switch 2. The Switch games getting these updates include:

Hyrule Warriors: Age of Imprisonment

Hyrule Warriors: Age of Imprisonment is a new game set in the world of Zelda that tells the story that leads into The Legend of Zelda: Tears of the Kingdom. This appears to be similar to how Hyrule Warriors: Age of Calamity told the story of a war that led to the events of Breath of the Wild. The teaser shows Zelda discovering that she’s arrived in the past of Hyrule, and the game will expand on how she gets involved in the corresponding Imprisonment War.

Nintendo Switch 2 games

Several other first- and third-party games were spotlighted during the Switch 2 Direct. These include Donkey Bananza, one of the first 3D platforming games featuring DK since 1999’s Donkey Kong 64. Kirby will also return to the racing genre in Kirby Air Riders, which comes more than 20 years after the GameCube racer Kirby’s Air Ride. DragXDrive will use mouse controls to control a futuristic wheelchair basketball game in which players will simulate push and pull motions to control their character.

An onslaught of Switch 2 third-party games were quickly shuffled through during the Direct, which I list below. An unnamed James Bond game is in development at Hitman studio IO Interactive, as is a darker title from Elden Ring creator FromSoftware called The Duskbloods, which will be exclusive to the Switch 2.

The full list of announced Nintendo Switch 2 games includes:

Borderlands 4
Bravely Default Flying Fairy HD Remaster

Nintendo GameCube library coming to Switch 2

The Nintendo Switch Online game library will add GameCube games to the Switch 2. On launch day, these games will initially include The Legend of Zelda: The Wind Waker, SoulCalibur 2 and F-Zero GX, with each game getting enhanced graphics. Online multiplayer will also be added to certain titles. Super Mario Sunshine, Super Mario Strikers and Luigi’s Mansion are among the games set to arrive later. At launch, Nintendo will also sell a GameCube controller, which will be wireless and include a C button for GameChat.

Which Nintendo Switch Accessories Will Work With the Nintendo Switch 2?

The next-gen Switch console has many physical changes, but that doesn’t mean you’ll have to get rid of all your gear for the original Switch.

Nintendo detailed the highly anticipated Switch 2 on Wednesday. We still have to wait a few more months before we can actually get our hands on it — June 5, to be precise — but that gives us plenty of time to make sure we have all the extra accessories we’ll need. On the upside, many of the accessories for the original Nintendo Switch will work with the Switch 2, but some important ones won’t.

Controllers

Joy-Con

The Switch 2 will come with its own set of updated Joy-Cons, but you can still use the original ones. They won’t attach physically to the Switch 2, as the new Joy-Cons are larger and attach magnetically, but you can pair the original Joy-Cons wirelessly. That way, you can still play with your family and friends without buying extras.

Pro Controller

Nintendo’s excellent Pro Controller also got an upgrade for the Switch 2, but as with the Joy-Cons, the original Pro Controller will work fine with the Switch 2. It will pair wirelessly with the console and can be charged via a USB cable from the Switch 2 dock. The new Pro will have some decent upgrades, like enlarged buttons and triggers, GameCube-esque ergonomics, and programmable back paddles, but it will also cost $80, so if you don’t feel you need to upgrade, you won’t have to.

Other Nintendo controllers

Nintendo also clarified that all the wireless versions of the NES, SNES, N64 and Sega Genesis controllers will work wirelessly with the Switch 2. However, it also said that not every game would be compatible, but we don’t know yet which games those would be. It’s probably safe to assume all games supporting those controllers (also compatible with the Switch 2) would work, but we’ll update this once we know more.

Third-party controllers

This is the big question mark at the moment. We have not been able to confirm anything from either Nintendo or other controller manufacturers if third-party controllers will work with the Switch 2. I assume that since the original Pro Controller will work with the Switch 2, at the very least, officially licensed third-party controllers will work, but as of publish time, we have not had any confirmation about support for third-party controllers on the Switch 2. One vendor I spoke with confirmed it is currently in talks with Nintendo about compatibility but couldn’t share any details.

MicroSD cards

One of the biggest (and most welcome) upgrades to the Switch 2 is an 8x increase in internal storage from 32GB to 256GB. That means a microSD is no longer an immediate must-have accessory. That’s also good because not every microSD card that worked with the original Switch will work with the Switch 2.

Nintendo specified that only microSD Express cards will work with Switch 2. You can still view screenshots and videos from your non-Express microSD cards, but you won’t be able to save or load games or save data to them. You can tell if your microSD card is Express because it will have a little EX printed on it.

Bluetooth headphones

The original Nintendo Switch infamously did not have Bluetooth capabilities, so you had to plug in headphones or buy an adapter. Nintendo remedied this with updated Switch versions and kept that functionality for the Switch 2. That means all your favorite Bluetooth headphones should work just fine with your new Switch 2.

Docks

The Switch 2 dock is also getting a big upgrade. It’s larger with rounded corners and now supports 4K resolution at 60 frames per second, a welcome upgrade for a modern game console. That being said, for households with multiple Switch consoles and TVs, you may not want to buy extra Switch 2 docks to use around your home.

However, Nintendo confirmed that the original Switch Dock is incompatible with the Switch 2, which also means it’s likely the original Switch will not work in the Switch 2 Dock.

Third-party docks

Several docks not made by Nintendo work just fine with the first-generation Switch, so there’s no reason to expect they would not be compatible with the Switch 2 as long as they provide adequate power. However, once again, we’ve not had any confirmation, so we can’t say for sure.

Chargers, cables and adapters

Chargers

The first-generation Switch was notoriously fickle with non-Nintendo chargers, particularly when docked, and the Switch 2 looks likely to continue that trend. The Switch 2 has a different power input from the original Switch so that the original Switch charger won’t work for TV mode with the Switch 2. You can still charge the Switch 2 with it by plugging it in directly, but that’s it.

We also don’t know anything about third-party chargers for the Switch 2 yet. There were several that worked perfectly fine with the original Switch, but we don’t yet know the power draw of the Switch 2, so we can’t say for sure which chargers will work. Hopefully, we’ll find out more closer to launch, but for right now, the only charger that we know will work for TV mode with the Switch 2 is the charger that comes with it.

Cables

The Switch 2 most likely supports HDMI 2.1, which means the HDMI cable that came with the original Switch won’t work. Nintendo has confirmed as much, though, as with most other accessories, it hasn’t given specifics as to whether third-party HDMI cables will work or not. We’ll have to wait to find out. The Switch 2 will have an HDMI cable, so at least there’s that.

Adapters

Nintendo has confirmed that the only adapter that works with the Switch 2 is the GameCube Controller adapter. This lets you connect a wired GameCube controller to the Switch Dock, and Nintendo says it can be used in TV mode while connected to a Switch 2 Dock. We don’t know anything else about any other adapters at this time.

Nintendo did give us quite a lot of information about the Switch 2 today, including the price, most of the key upgrades, and the launch date, but as you can see, there’s still a lot we don’t know. We’ll continue to update this list and our other coverage of the Nintendo Switch 2 as we learn more.
