Astronomers are watching over 2,200 potentially hazardous asteroids larger than one mile across. It is rare that any will pose a real danger. The Chixculub asteroid impact 66 million years ago is what anyone interested in seeing would want to see.

There is a new web app that gives asteroid impact fanatics a chance to ask questions. The app was described as "morbidly informative" by PC Gamer.

It's easy to use the asteroid launcher. You can choose from asteroids made from iron, stone, carbon, or gold, as well as comets and asteroids made from iron, stone, carbon, or gold. You can launch a asteroid by selecting ground zero on a map anywhere in the world.

An asteroid impact can kill more than one person.

In 2029, I'm going to drop an asteroid similar to99942 Apophis on Los Angeles. L.A., I'm sorry.

A fireball would burn most of the city and leave over 5 million people dead. The human eardrums would be torn as far as Santa Clarita. There are trees torn down as far as San Bernardino or Ventura. A magnitude 6.9 earthquake could be felt as far away as Bakersfield or San Diego.

Neil Agarwhal, a coder, based the app on several scientists' academic work in order to calculate the effects of an asteroid hit. Alex Wellerstein created a website that mimics the effects of dropping a nuclear weapon on the world.
