SOLAR SYSTEM

Detailed explanation-1: -An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them. A satellite can also be man-made, like the International Space Station.

Detailed explanation-2: -The answer to why the bigger objects are round boils down to the influence of gravity. An object’s gravitational pull will always point towards the centre of its mass. The bigger something is, the more massive it is, and the larger its gravitational pull.

Detailed explanation-3: -The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field.

Detailed explanation-4: -Orbiting objects, which are called satellites, include planets, moons, asteroids, and manmade devices.

Detailed explanation-5: -Moons – also called natural satellites – come in many shapes, sizes and types. They are generally solid bodies, and few have atmospheres. Most planetary moons probably formed out the discs of gas and dust circulating around planets in the early solar system.
