Satellites are fascinating devices that orbit our planet and serve a variety of crucial functions. Whether you're using your smartphone, watching TV, or checking the weather, satellites play an integral role in our daily lives.

What Are Satellites?

At its core, a satellite is any object that orbits a larger body, such as a planet or a moon. While there are natural satellites—like our Moon—when we refer to satellites in this article, we mean artificial ones created by humans. These man-made satellites are launched into space to serve specific purposes. They enhance communication, navigation, weather forecasting, and scientific research, making them essential to modern life.

How Do Satellites Work?

Satellites orbit at different altitudes—some close to Earth, others fixed above the equator. They use antennas to communicate, sensors to collect data, and solar panels for power.
