WESTLAFAYETTE, Ind. - Purdue University on Wednesday (Nov. 3) unveiled ''Impact: Earth!'' a new website that allows anyone to calculate the potential damage a comet or asteroid would cause if it hit the Earth.. The interactive website is scientifically accurate enough to be used by homeland security and NASA, but user
Whilethe most deadly impact killed around 117 million people, many asteroids posed no threat at all, the simulations revealed. More than half of asteroids smaller than 60 meters across — and

Thefictitious asteroid in the simulation was called 2021PDC. In NASA's scenario, it was first "spotted" on April 19, at which time it was thought to have a 5 percent chance of hitting our planet on October 20, six months after its discovery date. But Day 2 of the exercise fast-forwarded to May 2, when new impact-trajectory calculations showed
OnThursday, Jan. 26, a small near-Earth asteroid will have a very close encounter with our planet. Designated 2023 BU, the asteroid will zoom over the southern tip of South America at about 4:27 p.m. PST (7:27 p.m. EST) only 2,200 miles (3,600 kilometers) above the planet’s surface and well within the orbit of geosynchronous satellites.
Hereis the code for running the simulation with the impact frequency for the smallest asteroid category. For those of us alive in 2013, we already had one asteroid event (although not an impact) when a near Earth asteroid 20 m (0.02 km the units used here) in diameter exploded over the Chelyabinsk oblast in Russia. However, because the ubjae.
