The orbit of a 1.5 x 1010 kg comet around the Sun is elliptical, with an aphelion distance of 33.0 AU and perihelion distance of 0.855 AU. (Note: 1 AU = one astronomical unit = the average distance from the Sun to the Earth = 1.496 × 1011 m.) (a) What is its orbital eccentricity? (b) What is its period? (Enter your answer in yr.) yr (c) At aphelion what is the potential energy (in J) of the comet-Sun system?
