| Static information such as semi-major axis of ellipse, apogee and perigee altitudes, and anomalistic and nodal periods of satellite orbits. |
| Contrasting full moons seen near perigee and apogee indicate how much the apparent size of the Moon varies each month. |
| In a second class of orbit, the perigee and apogee heights are respectively 26,000 and 46,000 km, giving a 24 h orbital period. |
| However, supermoon came to denote the more-restrictive meaning of a full moon at perigee. |
| Maximum gravitation force occurs when a syzygy and perigee occur on the same day as perihelion. |
| The progress of the Moon from one perigee to the next is known as the anomalistic lunar cycle and takes 27 days, 13 hours and 18 minutes. |
