Satellite

A satellite is an object that orbits around a larger object. In the context of space and technology, a satellite is a man-made object that is launched into space and orbits the Earth, other planets, or celestial bodies. Satellites have a wide range of applications, including communication, weather monitoring, navigation, scientific research, and reconnaissance.

Types of Satellites

There are several types of satellites, including:

• Communication Satellites: These are used for transmitting television, telephone, and internet signals around the world.
• Weather Satellites: These are used to monitor and study weather patterns and phenomena.
• Navigation Satellites: These provide positioning and timing information for navigation purposes, such as GPS (Global Positioning System) satellites.
• Observational Satellites: These are used for scientific research, Earth observation, and surveillance.

How Satellites Work

Satellites are launched into space using rockets and are placed into specific orbits around the Earth or other celestial bodies. Once in orbit, satellites are able to perform their designated functions, such as transmitting signals, capturing images, or collecting data. They are powered by solar panels and use onboard computers and communication systems to function.
