What Is a Satellite?

Imagine laying out in the grass on a summer night and looking up into the big, dark sky. You see some twinkling stars, but what really catches your eye is the bright, full moon. It's so bright that it seems to light up your backyard like a night light. And while you're looking at that bright white ball in the sky, you might not have thought about the fact that it revolves around the earth and is a satellite!

A satellite is anything that orbits, or revolves around a bigger object. When you think about satellites, you might think of a science fiction movie where scientists are launching a top secret, man-made satellite into space, but there are natural satellites, too!

Examples of Natural Satellites

The moon is an example of a satellite that you probably see on most nights. It orbits around the earth, like a hula-hoop spins around your waist.

And you might not even realize you live on a satellite. The earth orbits the sun, which means your home, toys, computer, and favorite sneakers are all sitting on a satellite!

But moons and planets aren't the only natural satellites. Asteroids and comets are satellites, too. Halley's Comet is a satellite of the sun, even though it can take as many as 76 years for one orbit.

Man-Made Satellites & What They Do

There are also thousands of man-made satellites, which are machines that people have launched into space to do different jobs. The first man-made satellite was called Sputnik 1 and it was sent into space by the Soviet Union in 1957. The first US satellite was Explorer 1 and it was launched in 1958.

Some of the satellites we rely on today include:
