Abstract
The distance between spacecraft operating on elliptical orbit and the earth changes constantly within an orbit cycle, that is, the eccentricity of the orbit, which the spacecraft is on is not zero, and the point with the smallest distance from spacecraft operating under this condition to the earth is called perigee, and the farthest point is called apogee.
