SOLAR SYSTEM

Detailed explanation-1: -These are: GEO (Geostationary Earth Orbit) at about 36, 000km above the earth’s surface. LEO (Low Earth Orbit) at about 500-1500km above the earth’s surface. MEO (Medium Earth Orbit) or ICO (Intermediate Circular Orbit) at about 6000-20, 000 km above the earth’s surface.

Detailed explanation-2: -A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35, 800 kilometers (22, 300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east).

Detailed explanation-3: -Telecommunications satellites are usually placed in geostationary Earth orbit (GEO). GEO is a circular orbit 35 786 kilometres above Earth’s equator and follows the direction of Earth’s rotation.

Detailed explanation-4: -As of 2018, about 90% of satellites orbiting Earth were in low Earth orbit or geostationary orbit; geostationary means the satellites stay still at the sky. Some imaging satellites chose a Sun-synchronous orbit because they can scan the entire globe with similar lighting.
