From Wikipedia, the free encyclopedia

In astrodynamics Orbital angular momentum vector is a vector perpendicular to the orbital plane that is used in calculations of orbital parameters from orbital state vectors.

Orbital angular momentum vector is defined as:

where:

• is orbiting body's position vector,
• is orbiting body's velocity vector.
