Detailed explanation-1: -EXPLANATION: The satellite moves on a circular path around the earth. There is a gravitational force by the earth on satellite and a centrifugal force on the satellite.
Detailed explanation-2: -The Sun for planets or the central planet for satellites occupies one of the focal points of the ellipse. Since the planets and most satellites of the solar system revolve in an almost circular motion around the Sun or their parent planet, their orbital eccentricity is generally much closer to 0 than to 1.
Detailed explanation-3: -Think of an orbit’s two focus points, or foci, as its centers. In a perfectly circular orbit, they are at the center of the circle. Most orbits follow the shape of an ellipse, and have two foci.
