When an object, either man-made or natural, orbits a planet it is called a satellite.
Yes there are millions of objects that orbit Saturn.
Many smaller objects cross Eris' orbit, so it does not dominate its orbital path. An object must clear its orbit of other objects to be considered a planet.
Gravity is what keeps objects in orbit around a planet from flying off into space. The gravitational pull between the planet and the objects creates a centripetal force that balances the outward motion, keeping them in a stable orbit.
NO, the orbit of any planet or moon is determined by the size of the two objects involved (example: the Earth and the Sun) and the distance between those two objects: the closer the objects are to each other and the bigger one of the objects is, the stronger the gravitational pull ( large objects have stronger forces on other smaller objects). The orbit of a planet has nothing to do with the Sun's heat.
The planet Saturn
Through gravitational pull. The largest object will have smaller objects orbit it (objects close in size will orbit each other, but no planet is close to the size of the sun)
asteroids
Both asteroids and planets are objects that orbit the sun.
In order the planets and objects are:MercuryVenusEarthMarsAsteroid BeltJupiterSaturnUranusNeptunePluto (It's a dwarf planet)
Generally, although objects that orbit dwarf planets and smaller objects such as asteroids can also be called moons.
The definition of a planet has nothing to do with its composition. A planet is any spherical object orbiting the Sun that has cleared its orbit from other objects.
Both moons and planets are objects in space that orbit a larger body.
