List of orbits


The following is a list of types of orbits:

Contents

Centric classifications


For orbits centered about planets other than Earth and Mars, the orbit names incorporating Greek terminology is less commonly used

Altitude classifications for geocentric orbits


Inclination classifications


Directional 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


Orbits in galaxies or galaxy models


Special classifications


Pseudo-orbit classifications

Notes


  1. ^ Orbital periods and speeds are calculated using the relations 4π2R3 = T2GM and V2R = GM, where R = radius of orbit in metres, T = orbital period in seconds, V = orbital speed in m/s, G = gravitational constant ≈ 6.673×1011 Nm2/kg2, M = mass of Earth ≈ 5.98×1024 kg.
  2. ^ Approximately 8.6 times when the moon is nearest (363 104 km ÷ 42 164 km) to 9.6 times when the moon is farthest (405 696 km ÷ 42 164 km).
