An asteroid whose mass is .0002 times the mass of Earth, is in a circular orbit about the sun at a distance that is twice the earth's distance from the sun. The mass of the sun is M= 1.9E30 kilograms and the Earth-Sun distance is 1.5E11 meters.
Find the period of this asteroid, in years.
For a satellite of mass m, in circular orbit of radius r, around a body of mass M, we apply 'net force = m a' in which the net force on the satellite is ...
The expert examines satellite's period in orbit around the sun. The period of the asteroid is found.
