SOLAR SYSTEM

Detailed explanation-1: -A low Earth orbit (LEO) is, as the name suggests, an orbit that is relatively close to Earth’s surface. It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth – which is low compared to other orbits, but still very far above Earth’s surface.

Detailed explanation-2: -Polar orbit and Sun-synchronous orbit (SSO) Polar orbits are a type of low Earth orbit, as they are at low altitudes between 200 to 1000 km. Sun-synchronous orbit (SSO) is a particular kind of polar orbit. Satellites in SSO, travelling over the polar regions, are synchronous with the Sun.

Detailed explanation-3: -Satellites in LEO typically take between 90 minutes and 2 hours to complete one full orbit around the Earth. Low altitudes in combination with short orbital periods make LEO satellites ideally situated for remote sensing missions, including Earth observation and reconnaissance.

Detailed explanation-4: -More than 3, 000 satellites are in low Earth orbit (LEO), which is where you will find satellites commonly used for communications and remote sensing satellite systems.
