List of orbits

Various Earth orbits to scale; innermost, the red dotted line represents the orbit of the International Space Station (ISS); cyan represents low Earth orbit, yellow represents medium Earth orbit, and the black dashed line represents geosynchronous orbit. The green dash-dot line represents the orbit of Global Positioning System (GPS) satellites.

The following is a list of types of orbits:

Centric classifications

Altitude classifications for geocentric orbits

Inclination classifications

Eccentricity classifications

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.

Synchronicity classifications

Geostationary orbit as seen from the north celestial pole. To an observer on the rotating Earth, the red and yellow satellites appear stationary in the sky above Singapore and Africa respectively.

Orbits in galaxies or galaxy models

Special classifications

Pseudo-orbit classifications

A diagram showing the five Lagrangian points in a two-body system with one body far more massive than the other (e.g. the Sun and the Earth). In such a system, L3L5 are situated slightly outside of the secondary's orbit despite their appearance in this small scale diagram.
