KOMPAS.com – Earth has one natural satellite, the Moon. However, it turns out that not only Earth has the Moon as a satellite, because every planet in the Solar System must have its own natural satellite.
Natural satellites are also owned by a number of planets in this Solar System, such as the planet Mars with its moons Fobos and Deimos, or Jupiter which has several moons and the largest of them is Ganymade, and Saturn which has dozens of natural satellites orbiting this ringed planet.
Quoted from the page NASAWednesday (8/2/2017) a satellite is an object that moves around or orbits another object that is larger.
Generally, the term satellite is widely used to refer to large man-made technology to be placed in orbit and can transmit internet signals.
Maybe there are still many people who wonder why the Moon is called a natural satellite for the planets in the Solar System?
So, to answer the secret of the universe, this time we discuss about the moon as a natural satellite.

NASA explains that the Moon is called a satellite because it moves around the planets, including Earth. Moon is Earth’s satellite or Earth’s natural sattelite.
Natural satellites are objects in outer space that orbit around other objects that are larger in size.
Thus, any large object that orbits around the planet is referred to as the Moon.
Unlike other planets, as is known, Earth has one Moon which takes 27.3 days to orbit and moves at an orbital speed of 1 km per second.
The moon is thought to have formed about 4.51 billion years ago, with a diameter of 3,474 km. Meanwhile, the average distance from Earth to the Moon is 384,400 km.
The moon appears to move across the sky from east to west, in the same direction as the sun.
However, this assumption turned out to be incorrect, because the Moon, this natural satellite, orbits the Earth from west to east.
