Satellites are part of our daily lives. We use them when we drive sometimes, use the internet, and many more things. But what are they? I will explain what they are, the two types of satellites and their uses, where they are, how many are orbiting earth and more in this article. Please drop a comment on the bottom of the page if you liked it.
There are two types of satellites. One type most planets have and the second, only two to 6 planets have. These two types are natural satellites and artificial satellites. Natural satellites are moons, rocks, asteroids orbiting the planet, such as the two moons, Phobos and Deimos for Mars, the many moons of Jupiter, and the Moon for Earth. These natural satellites help in the tide, the planet’s orbit, etc.
Artificial satellites are the satellites that are made by man, that orbit Earth, the moon and other planets in the solar system, and land on the planets and asteroids to conduct experiments and map the land. These various other satellites are hugely essential for humans. They help in television broadcasting, GPS, communication and calls, scientific research of other planets, weather forecasting and many more things.
Satellites that orbit the Earth are in the region called ‘lower earth orbit’ is till around 2,000 km high and orbit the earth in many hundreds of orbits. These satellites can move with speeds up to 28,800 km per hour. Bullet trains go at a speed of 320 km per hour. These satellites can go 90 times this speed. If a small tiny metal part as big as a pea flew at those speeds, it could shred our satellites to pieces. Currently, there are 9,900 satellites orbiting earth.
