What is a geostationary satellite, commonly used for communications and weather monitoring?
AA satellite that orbits the moon rather than Earth
BA satellite that only operates during nighttime
CA satellite that remains fixed at a single point relative to Earth's surface because its orbital speed matches Earth's rotation
DA satellite that never orbits Earth at all
Explanation
A geostationary satellite orbits Earth at a specific altitude and speed that exactly matches the planet’s own rotational speed, meaning the satellite appears to remain fixed over the same point on Earth’s surface at all times as viewed from the ground. This stationary positioning makes geostationary satellites especially useful for applications like television broadcasting, weather monitoring, and certain communications systems, since ground-based antennas can remain pointed at a single fixed location in the sky. Achieving this specific type of orbit requires positioning the satellite at a precise altitude of roughly 35,786 kilometers above the equator.
