angle between a reference plane and the plane of an orbit
(Redirected from Inclination)
One of the planes is the standard, or reference. The galactic plane of a galaxy is often used as the reference.
- For a planet's orbit, the inclination is the angle to the ecliptic plane.
- For a moon, an inclination of 0 degrees means the orbiting body orbits the planet in its equatorial plane, in the same direction as the planet rotates.
