Comet Halley moves in an elongated elliptical orbit around the sun. At perihelion the comet distance is 8.75 x 107 km from the sun; at aphelion, it is 5.26 x 109 km from the sun. Find the semi-major axis, eccentricity, and the period of the orbit. Comet Halley was at perihelion in early 1986; when will it reach the perihelion again? G = 6.67 x 10-11 N.m2/kg2; Mass of sun = 1.99 x 1030 kg.
