1. What would happen if earth absorbed all of the heat from the sun? A. Earth would become too cold. B. Earth would be too hot. C. Earth would eventually stop recieving heat. D. Earth would lose all of it's own heat.
The period of revolution of a planet around the sun is the time it takes for the planet to complete one orbit of the sun. The period, P years, is give by Kepler's third law P^2=D^3, where D is the average distance from the sun in astronomical units (AU).
