A satellite is a object with mass which revolves around the another object which is heavier than that. For instance Moon is a Natural Satellite to Earth because it revolves or moves around the Earth.The Satellites which are man-made are known as Artificial Satellite, for example: sputnik 1, Rohini, etc.

Simply satellite is somthing which revolves around the planet.
hav a nice day ;-)

Satellite:
Satellites are objects that orbit around larger bodies in space, such as planets or stars. They can be natural, like moons, or artificial, man-made objects launched into space for various purposes. Satellites play a crucial role in communication, navigation, weather forecasting, scientific research, and defense.

Natural Satellites:
- Natural satellites are celestial bodies that orbit planets. For example, Earth has one natural satellite, the Moon.
- These satellites are formed through natural processes like gravitational capture or accretion.

Artificial Satellites:
- Artificial satellites are human-made objects launched into space to perform specific tasks.
- They are usually equipped with communication antennas, sensors, and other instruments for their designated purpose.

Types of Satellites:
- Communication Satellites: These satellites are used for transmitting signals for television, radio, internet, and telephone communication.
- Weather Satellites: Weather satellites monitor and track weather patterns, helping in forecasting and predicting natural disasters.
- Navigation Satellites: Navigation satellites provide accurate positioning and timing information for GPS systems.
- Scientific Satellites: Scientific satellites are used for conducting research in space, studying planets, stars, and other celestial phenomena.
- Military Satellites: Military satellites are used for surveillance, reconnaissance, and communication in defense operations.

Orbit:
- Satellites can orbit the Earth in various orbits, such as low Earth orbit (LEO), geostationary orbit (GEO), and polar orbit, depending on their purpose.
- The orbit determines the satellite's coverage area, visibility, and communication latency.

Applications:
- Satellites have revolutionized communication, enabling global connectivity.
- They provide vital data for weather forecasting, disaster management, and environmental monitoring.
- Satellites play a crucial role in navigation, ensuring accurate positioning and timing for various applications.
In conclusion, satellites are indispensable tools for modern society, facilitating communication, scientific exploration, and various essential services.
