The asteroid belt between Mars and Jupiter consists of many fragments (which some space scientists think came from a planet that once orbited the Sun but was destroyed).
(a) If the center of mass of the asteroid belt is about 2 times farther from the Sun than the Earth is, how long would it have taken this hypothetical planet to orbit the Sun? ___yr
(b) Can we use this data to deduce the mass of this planet?
Use Keplers Law for this. You can use the ratio of Earth.
