Moon – Our Natural Satellite

Our moon is the natural satellite of the Earth. Growing up, we have heard many tales about the moon, but only in school, did we learn about its significance. The Moon is an astronomical body that moves around our planet on its orbit. It is the only natural satellite of our planet. When compared to all the other natural satellites of the different planets in our solar system, the moon is the fifth-largest.

Do All Planets Have A Natural Satellite In Our Solar System?

There are no natural satellites in Mercury and Venus. Our Earth has one satellite – the moon. Phobos and Deimos are small natural satellites of Mars. Apart from the natural satellites, there are various other man-made artificial satellites orbiting our planet and space. These artificial ones take pictures of the surface, monitor and predict weather changes and find out more about various celestial bodies such as meteors, asteroids, comets, and other galaxies.

Why Is Moon Called A Natural Satellite?

A natural satellite is a small astronomical body that orbits around a larger astronomical body. It is held in its own orbit by the gravitational pull of the larger body. Not only moons but also small galaxies that orbit around larger galaxies are known as natural satellites. The artificial satellites made by man are also designed in such a way that they orbit a larger body – our planet on a fixed orbit. Artificial satellites are used for communications, such as TV signals, phone calls, etc. These are also used for the Global Positioning System or the GPS.

Why Is Moon Called The Natural Satellite Of The Earth?

The Earth is also a satellite because it orbits around the Sun. Similarly, the Moon orbits around the Earth and hence is called the satellite of the Earth. The term satellite refers to anybody in space that moves around our planet or around another body in space. Both Earth and Moon are natural satellites.

Does Earth Have 3 Natural Satellites?

Apart from the moon, there are several near-Earth objects, known as NEOs that orbit around the Earth too. These are sometimes referred to as ‘Second’, ‘Third’, or ‘Other’ Moons. But the only natural satellite of the Earth is the Moon.

What Would Happen If The Earth Had Two Natural Satellite?

If there were more than one moons orbiting the Earth, the amplitude of the tides could be either larger or smaller, depending upon the effects of each satellite. It could also lead to two high tides in one day. Moreover, the cycle of the tides could be irregular too.

What Lead To The Creation Of Our Natural Satellite?

Our moon was created as a result of a giant-impact hypothesis, which is known as the Big Splash or the Theia Impact. This hypothesis suggests that the moon was created out of the left-over debris resulted from a collision between our planet and another astronomical body, probably the size of Mars. Furthermore, this phenomenon must have occurred 4.5 billion years ago.
