// ORBITAL LOGISTICS AND PROPULSION TERM

Orbital Plane

The imaginary flat surface in which a satellite's orbit lies, passing through the center of the celestial body it's orbiting.

TECHNICAL DEFINITION

The Orbital Plane is the two-dimensional plane containing an orbiting body's trajectory and the center of the primary body, defined by its inclination and the right ascension of the ascending node, crucial for understanding orbital orientation in space.

BACKGROUND

Private spaceflight companies include non-governmental or privately owned entities focused on developing and/or offering equipment and services geared towards spaceflight, both robotic and human. This list includes both inactive and active entities.
