Asteroid moons are asteroids that orbit larger asteroids. The orbital radius and angular velocity of the planet in the elliptical orbit will vary. It is the major cause of orbital decay for satellites in low Earth orbit. Apollo lunar missions would begin with a nominal circular Earth parking orbit. Asgardia intends to launch a series of satellites into Earth orbit. Its payload capacity is expected to be more than to lunar orbit. Remaining four satellites are in inclined geosynchronous orbit (GSO). LEO satphones utilize satellites in low Earth orbit (LEO). Due to atmospheric drag, satellites do not usually orbit below . Rogue planets do not orbit any star. Sectors typically orbit planets, within a star system. There are several different periods associated with the lunar orbit. The capture of an asteroid from a heliocentric orbit is not always permanent. These moons all orbit beyond the E Ring. Teams compete for a variety of prizes in lunar orbit or deep space.
