 Orbital inclination change

Orbital inclination change refers to the modification of the angle between the orbital plane of a celestial body (such as a planet, moon, or satellite) and a reference plane, typically the equatorial plane of the body it orbits or a standard plane like the ecliptic. The inclination is measured in degrees, with an inclination of 0° indicating an orbit that lies in the same plane as the reference plane, while an inclination of 90° indicates a polar orbit.
