Moons are 'Natural Satellites' Earth's Moon is named Luna, as earth is Terra
Satellites in polar orbits travel from the North Pole to the South Pole and back again with each orbit, providing global coverage. Some examples of satellites in polar orbit are the NOAA series of weather satellites, the Aqua and Terra Earth observation satellites, and the International Space Station.
Yes they are.
Though now retired, the space shuttle was able to 'capture' satellites for repair and replace then in their correct orbit.
Various satellites have explored Earth, including the Landsat series, which has provided detailed imagery for over four decades, and the Terra satellite, part of NASA's Earth Observing System, which monitors climate and environmental changes. The Sentinel satellites, part of the Copernicus program, offer high-resolution data for land and ocean monitoring. Additionally, the GOES (Geostationary Operational Environmental Satellites) provide real-time weather data and monitoring. These satellites collectively enhance our understanding of Earth's systems and changes.
Physics. Specifically, it's a combination of inertia and gravity.
