An asteroid is in orbit at 4 times the Earth's distance from the Sun. What is its period of revolution?
a. one fourth year
b. 4 years
c. 8 years
d. 16 years

Question 2

For any object orbiting the Sun, Kepler's law may be written T2 = kr3 . If T is measured in years and r in units of the Earth's distance from the Sun, then k = 1 . What, therefore, is the time (in years) for Mars to orbit the Sun if its mean radius from the Sun is 1.5 times the Earth's distance from the Sun?
a. 1.8 years
b. 2.8 years
c. 3.4 years
d. 4.2 years
