Question

Suppose a 10-meter diameter rocky meteoroid were found on a certain collision course with Earth. It will hit Earth with a velocity of 20 km/s. What would the Torino scale ranking be for this object? You can use the Solar Systems Collisions website (http://janus.astro.umd.edu/astro/impact/) to determine impact energy. A. 5 - the Torino scale is based on chance of impact and energy of impact: the object gets 5/5 points for certain collision, but 0/5 for small size. It is the year 2870 and your great-great-great-....-greatgranddaughter has refined the orbit of asteroid 1950DA. She there is a 99% chance of 1950DA hitting Earth in 10 years (in 2880). Given that asteroid 1950DA is a rocky asteroid 1.2km in diameter, which method should your descendant propose to mitigate the chance of impact?
