What is a celestial body that revolves around a planet in the same way that a planet revolves around the Sun?

The correct answer is Satellite.

Key Points

• A satellite is a celestial body that revolves around a planet in the same way that a planet revolves around the Sun.
• Natural satellites, like moons, orbit planets due to the gravitational pull of the planet.
• Artificial satellites are human-made objects placed in orbit for various purposes, such as communication, weather monitoring, and scientific research.
• The Earth's moon is an example of a natural satellite.
• Satellites play a critical role in modern technology, enabling GPS, telecommunications, and Earth observation.

Additional Information

• Types of Satellites
  • Natural Satellites: These include moons or other celestial bodies naturally orbiting a planet. Example: Earth's Moon.
  • Artificial Satellites: Man-made devices launched into orbit for specific functions like communication, weather forecasting, and research.
• Geostationary Satellites
  • Orbit the Earth at the equator at the same rate that the Earth rotates.
  • Remain stationary relative to a point on the Earth's surface.
  • Commonly used for telecommunications and broadcasting.
• Low Earth Orbit (LEO) Satellites
  • Orbit at altitudes between 160 to 2,000 kilometers above the Earth.
  • Used for imaging, environmental monitoring, and some communication networks.
• Satellite Launch Vehicles
  • Rockets used to transport satellites into space.
  • Examples include NASA's Space Launch System (SLS) and ISRO's Polar Satellite Launch Vehicle (PSLV).
• Historical Milestones
  • Sputnik 1: The first artificial satellite, launched by the Soviet Union in 1957.
  • Explorer 1: The first American satellite, launched in 1958.
