When a satellite follows a non-circular orbit around the earth, the satellite's path is an ellipse with the center of the earth at one focus. The point of highest altitude in the elliptical orbit is called the apogee. When a satellite follows a non-circular orbit around the earth, the satellite's path is an ellipse with the center of the earth at one focus.
The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth's orbit) . The ecliptic is inclined only 7 degrees from the plane of the Sun's equator.
