712 = 472 a3 GM To practice solving for mass, solve this problem: A space probe is placed into orbit (r = 1400 meters) around a small asteroid. If it takes the space probe 3.5 days to orbit the asteroid, what is the asteroids mass? Enter your answer as in BILLIONS of kg (divide your answer by 1,000,000,000) to ONE decimal place. For example, if your answer is 85,280,550,740 you would enter 85.3
