Sepler's Third Law relates the period (P) it takes a planet to go around the Sun to the semi-major axis (a) of its orbit. Assume that the mass of the Sun is much greater than any of the planets (which it is), and measure P in years and a in astronomical units. The simplified relationship (formula) is:
P = √(a^3)
The following two orbits have the same value for a. How do their values of P compare?
