Definition of Satellite and its Types All

KOMPAS.com – Satellites fly high so they can see a very large surface of the Earth at one time. The satellite also has a clear view of space because it is above the clouds.

Satellites have an important role for life on Earth. With satellite, TV signals and phone calls can be sent to the satellite to be sent back to a different place.

Please note that there are two types of satellites, namely: natural satellite and artificial satellites man. In detail, the following is an explanation of the definition, types, and examples of satellites.

Simply, satellite is objects that orbit the planet. According to NASA, satellites are objects that move around larger objects.

Refers to the meaning put forward NASAEarth is a satellite because it orbits or revolves around the Sun, an object much larger than Earth.

Thus, the term “satellite” does not only refer to a device that is launched into space and moves around the Earth or other objects in space.

Types of satellites

As already stated, there are two types of satellites, namely natural satellites and artificial satellites. Natural satellite are objects in space that orbit larger objects, while artificial satellites are man -made objects that orbit larger objects in space.

Natural satellite

There are hundreds of natural satellites in the solar system. In fact, some asteroids have been found to have small satellites orbiting them.

An example of a natural satellite is the moon. The inner rocky planets, such as Mercury and Venus, have no natural satellites at all, whereas Earth has one natural satellite and Mars has two natural satellites.

Then, the gas giants, Jupiter and Saturn, as well as the ice giants, Uranus and Neptune, have dozens of natural satellites.

Artificial satellites

The first artificial satellite to fly into space was Sputnik, a Russian spacecraft that took off on October 4, 1957.

Since then, other countries have started to send their satellites into space until the benefits are felt by humans.

For example, weather satellites to improve weather forecasts to remote areas, land observation satellites to track changes in forests, water, and other parts over time, and telecommunications satellites to make telephone calls and send messages over long distances.
