For the following exercises, determine the pelar equaticm farm 0f the Orbit given the length of the major axis and eccentrieity fer the orbits of the comets (1r planets. Distance is given in astronomical units (AU). .318. Halley’s Comet: length of major axis = 35.88, eccentricity = 0.967 319. Hale—Bopp Comet: length of major axis 2 525.91, eccentricity = 0.995 320. Mars: length of major axis = 3.049, eccentricity = 0.0934 321. Jupiter: length of major axis = 10.408, eccentricity = 0.0484
