Moons Moons Co-orbital satellites are satellites that share the same mean orbit. Some trade orbits when the satellite closest to the planet or star catches up with the outer one. Saturn's moons Janus and Epimetheus are this type. More commonly, the satellites are positioned at the planet's L4 or L5 Lagrange points with respect to the Sun. Lagrange points are five positions in space where a small object with no other forces acting on it can be stationary with respect to two larger objects. Earth has a co-orbital satellite of this type, an asteroid named 2002AA29. ...more on Wikipedia about "Co-orbital satellite"
Interplanetary space is that part of outer space between planets in a solar system and its local star(s), many of which are binaries. Around any one planet, this space begins in the extended region where any amosphere, magnetic field and moons end, ceding dominance to the local star; in our case, the Sun. ...more on Wikipedia about "Interplanetary space"

The naming of natural satellites has been the responsibility of the IAU's committee for Planetary System Nomenclature since 1973. That committee is known today as the Working Group for Planetary System Nomenclature (WGPSN). ...more on Wikipedia about "Naming of natural satellites"
The common noun moon (not capitalized) is used to mean any natural satellite of the other planets. There are at least 140 moons within Earth's solar system, and presumably many others orbiting the planets of other stars. ...more on Wikipedia about "Natural satellite"
A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. ...more on Wikipedia about "Planetary ring"
A quasi-satellite is an object similar to a planet or satellite of the Sun, however its orbit encompasses its planet and the planet's star. ...more on Wikipedia about "Quasi-satellite"
