An artificial body placed in orbit round the earth or moon or another planet in order to collect information or for communication.

Orbit the Earth at the same rotational speed as the Earth, so they appear stationary relative to a fixed point on the Earth's surface.

Orbit at lower altitudes and are used for communication in areas where GEO satellites may have limitations.

Monitor and collect data about weather patterns and conditions.

Capture images and data about the Earth's surface for various purposes, including agriculture, forestry, and environmental monitoring.

Observe celestial objects and phenomena beyond Earth's atmosphere.

Designed to observe the universe in different wavelengths.

Form a constellation that provides precise location and timing information for navigation purposes.

Monitor activities on Earth for military and intelligence purposes.

Provide secure and accurate navigation and timing data for military operations.

Includes constellations like GPS, GLONASS, Galileo, and BeiDou, providing global navigation and positioning services.

Used to transport cargo, supplies, and equipment to space stations like the International Space Station (ISS).

Sent to explore and gather data about other planets, moons, asteroids, and comets.

Built and operated by educational institutions or amateur radio operators for educational and experimental purposes.

Human-made structures in orbit, such as the International Space Station (ISS), used for scientific research and international cooperation in space.
