Moons[]

A moon (also known as a natural satellite) is a celestial, non-artificial object that orbits a planet, the most common ones are the rocky moons and icy moons. Our Moon is a good example. They vary in size and shape and composition. If a moon is massive enough to pull the barycenter outside the surface of the parent planet, it becomes a binary planet, for example, Pluto and Charon orbits together in a barycenter. Any celestial object that is not man-made can be a moon for example, a rouge asteroid got captured by the strong gravitational pull, like for example a gas giant, the asteroid orbits the gas giant so long until it goes back to orbit the star again, or more unusually, gets on a collisional course of that planet, or one of its major moons. These are called captured asteroids and they can be found more commonly or not depending how massive the planet is, they are frequently very small but large, dwarf planets can have a chance from becoming a natural satellite, the only scenario that happened is the former dwarf planet, Triton getting gravitationally captured by Neptune, this event likely messed up the former major moons of Neptune, all of them either crashed the surface of Neptune or gets gravitationally slingshoted by Triton, becoming a new dwarf planet in the Kuiper belt.
