WebA planet is in an elliptical orbit around a distant star. At periastron (the point of closest approach to the star), the planet is rp = 4.10 x 108 km from the star and is moving with a speed of vp = 17.5 km/s. When the planet is at apastron (the point of greatest distance from the star), it is ra = 8.60 x 108 km from the star. thomas 1st earl of moray randolphWebJul 22, 2024 · A ( T) = π a b.
