Orbital Mechanics: A small space probe is put into circular orbit about a newly discovered moon of Saturn. The moon’s radius is known to be 550 km. If the probe orbits at a height of 1500 km above the moon’s surface and takes 2.0 earth days to make one orbit, determine the moon’s mass. Consider the total radial distance required to solve this problem. Be sure to perform all the necessary dimensional conversions to mks units.

Suppose that an asteroid traveling straight toward the center of the earth were to collide with our planet at the equator and bury itself just below the surface. What would have to be the mass of this asteroid, in terms of the earth's mass M , for the day to become 26.0% longer than it presently is as a result of the collision? Assume that the asteroid is very small compared to the earth and that the earth is uniform...
