4. Astronomers use a telescope to watch a small moon orbit a planet in our solar system. They find that it takes the moon 14 days to go around the planet once, and they estimate the radius of the moon's orbit is about 4.2 x 10² meters. a. From this information, estimate the mass of the planet. b. Using the mass you found in part (a), estimate the free-fall acceleration on the planet's surface if it has a radius of 3.8 x 106 meters.
