- If you stood on Earth during its formation, during which it captured about 1.6 ✕ 1011 particles per second, and watched a region covering 170 m2, how many impacts would you expect to see in an hour? (Notes: The surface area of a sphere is 4?r2. Hint: Assume that Earth had its current radius of 6,378 km.)Phobos, one of Mars’ moons, is very slowly spiraling down towards the planet. Do you think that Mars will one day have rings? Explain your reasoning,Imagine that you visit a planet orbiting another star and discover that it is heavily cratered, but its small moon is nearly crater free. Why would that be a surprise? Speculate what might have happened to those objects.
