Low orbits. Through a study of many lunar orbiting satellites, scientists have discovered that most low lunar orbits (LLO) are unstable. [5] Four frozen lunar orbits have been identified at 27°, 50°, 76°, and 86° inclination. NASA described this in 2006: Lunar mascons make most low lunar orbits unstable ... As a satellite passes 50 or 60 ...
Upon reaching its current location near 2.1 AU the ν 6 secular resonance and other related resonances would destabilize the orbits of the E-belt asteroids. Most would be driven onto planet-crossing orbits as their eccentricities and inclinations increased. Over a period of 400 million years impacts of the E-belt asteroids yield an estimated 9 ...
In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent object. Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites.
The orbits of Solar System planets are nearly circular. Compared to many other systems, they have smaller orbital eccentricity. [70] Although there are attempts to explain it partly with a bias in the radial-velocity detection method and partly with long interactions of a quite high number of planets, the exact causes remain undetermined. [70] [74]
Asteroids number in the hundreds of thousands. For longer lists, see list of exceptional asteroids, list of asteroids, or list of Solar System objects by size.

A top view of asteroid group location in the inner solar system A map of planets and asteroid groups of the inner solar system. Distances from sun are to scale, object sizes are not. Various dynamical groups of asteroids have been discovered orbiting in the inner Solar System.
The two outermost planets complete an orbit in 41 and 54.7 days, resulting in four orbits for every three. The innermost planet, meanwhile, completes six orbits in exactly the time the outermost ...
All eight planets in the Solar System have near-circular orbits. The exoplanets discovered show that the Solar System, with its unusually-low eccentricity, is rare and unique. [18] One theory attributes this low eccentricity to the high number of planets in the Solar System; another suggests it arose because of its unique asteroid belts.
