Retrograde Orbit Meaning Of. Retrograde motion is the orbital motion of a spatial body in a direction that is opposite of what is normal in a given system. An inclination of 0 degrees means the spacecraft orbits the planet at its equator, and in the same direction as the planet rotates.
The retrograde motion continues for a short time and then the motion switches back to prograde. An inclination of 0 degrees means the spacecraft orbits the planet at its equator, and in the same direction as the planet rotates.
