The asteroid Icarus, discovered in 1949, was so named because its highly eccentric elliptical orbit brings it close to the sun at perihelion. The eccentricity e of an ellipse is defined by the relation rp=a(1-e) where rp is the perihelion distance and a is the semi-major axis. Icarus has an eccentricity of 0.83 and a period of 1.1y. a)Determine the semi-major axis of the orbit of Icarus. b)Determine the perihelion and aphelion distances of thie orbit of Icarus.
