WebThe equatorial plane is the plane perpendicular to the axis of rotation of the central body. An inclination of 30° could also be described using an angle of 150°. The convention is that the normal orbit is prograde, an orbit in the same direction as the planet rotates. Inclinations greater than 90° describe retrograde orbits (backward). Thus: WebIn polar coordinates, the orbit equation can be written as [1] where is the separation distance between the two bodies and is the angle that makes with the axis of periapsis (also called the true anomaly ).
