| Heliosynchronous orbit | By analogy with the geosynchronous orbit, a heliosynchronous orbit is a heliocentric orbit of radius 24.360 Gm (0.1628 AU) such that the object's period of revolution matches the Sun's period of rotation. The heliostationary orbit is the heliosynchronous orbit of inclination zero and eccentricity zero. (references) | ||
