For orbits centered about planets other than Earth and Mars, the orbit names incorporating Greek terminology is less commonly used
- Mercury orbit (Hermocentric or hermiocentric): An orbit around the planet Mercury.
- Venus orbit (Aphrodiocentric or cytheriocentric): An orbit around the planet Venus.
- Jupiter orbit (Jovicentric or zenocentric): An orbit around the planet Jupiter.
- Saturn orbit (Kronocentric or saturnocentric): An orbit around the planet Saturn.
- Uranus orbit (Oranocentric): An orbit around the planet Uranus.
- Neptune orbit (Poseidocentric): An orbit around the planet Neptune.
Altitude classifications for geocentric orbits
- Low Earth orbit (LEO): geocentric orbits with altitudes below 2,000 km (1,200 mi).
- Medium Earth orbit (MEO): geocentric orbits ranging in altitude from 2,000 km (1,200 mi) to just below geosynchronous orbit at 35,786 kilometers (22,236 mi). Also known as an intermediate circular orbit. These are used for Global Navigation Satellite System spacecraft, such as GPS, GLONASS, Galileo, BeiDou. GPS satellites orbits at the height of 20,200 kilometers (12,600 mi) with an orbital period of almost 12 hours.
- Geosynchronous orbit (GSO) and geostationary orbit (GEO) are orbits around Earth matching Earth's sidereal rotation period. Although terms are often used interchangeably, technically a geosynchronous orbit matches the Earth's rotational period, but the definition does not require it to have zero orbital inclination to the equator, and thus is not stationary above a given point on the equator, but may oscillate north and south during the course of a day. Thus, a geostationary orbit is defined as a geosynchronous orbit at zero inclination. Geosynchronous (and geostationary) orbits have a semi-major axis of 42,164 km (26,199 mi). This works out to an altitude of 35,786 km (22,236 mi). Both complete one full orbit of Earth per sidereal day (relative to the stars, not the Sun).
- High Earth orbit: geocentric orbits above the altitude of geosynchronous orbit (35,786 km or 22,236 mi).
For Earth orbiting satellites below the height of about 800 km, the atmospheric drag is the major orbit perturbing force out of all non-gravitational forces. Above 800 km, solar radiation pressure causes the largest orbital perturbations. However, the atmospheric drag strongly depends on the density of the upper atmosphere, which is related to the solar activity, therefore the height at which the impact of the atmospheric drag is similar to solar radiation pressure varies depending on the phase of the solar cycle.
There are two types of orbits: closed (periodic) orbits, and open (escape) orbits. Circular and elliptical orbits are closed. Parabolic and hyperbolic orbits are open. Radial orbits can be either open or closed.
