What would happen if an meteor or asteroid the size of ______________, made of ______________, hit Earth at a speed of ______________?
There’s a web app for that. Check out Purdue’s Impact: Earth!
Have fun destroying the planet!!! (And learning about asteroid impacts of various sizes and energies, of course)
This is way cool!!
Simultaneously fascinating, terrifying, and perhaps a little buggy.
"The Earth is strongly disturbed by the impact, but loses little mass.
Depending on the direction and location the collision, the impact may make a noticeable change in the tilt of Earth’s axis (< 5 degrees).
Depending on the direction and location of impact, the collision may cause a change in the length of the day of up to 303 hours.
The impact does not shift the Earth’s orbit noticeably.”
"Global Damages: Day change: not significant.”
