Satellites By Jemima, Emily and Amelia <3
What is a satellite? • A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word "satellite" refers to a machine that is launched into space and moves around Earth or another body in space.
Natural and Artificial Satellites • Earth and the moon are examples of natural satellites • Thousands of artificial, or man-made, satellites orbit Earth. • We benefit from satellites as they transmit signals from space to our televisions and radios and they allow us to see the solar system in more detail.
Why do satellites stay in their orbits? • Satellites stay in their orbits because of the gravitational potential.
