Planet 1 and planet 2 are both in circular orbits around the same central star. The orbit of planet 2 has a radius that is much larger than the radius of the orbit of planet 1. This means that:
A. the period of planet 1 is greater than the period of planet 2 and the speed of planet 1 is greater than the speed of planet 2
B. the period of planet 1 is greater than the period of planet 2 and the speed of planet 1 is less than the speed of planet 2
C. the period of planet 1 is less than the period of planet 2 and the speed of planet 1 is less than the speed of planet 2
D. the period of planet 1 is less than the period of planet 2 and the speed of planet 1 is greater than the speed of planet 2
E. the planets have the same speed and the same period
