SOLAR SYSTEM

Detailed explanation-1: -Fun Facts about Satellites: Satellites travel at 18, 000 miles per hour. That means in a given day, satellites can travel the entire circumference of the Earth about 14 times.

Detailed explanation-2: -Satellite orbit map. This diagram shows the relative distance from Earth of the three satellite orbits, with low earth orbit closest to the earth at 160 – 2, 000km (99 – 1243 miles), and geostationary orbit the furthest away, at 35, 786 km (22, 236 miles).

Detailed explanation-3: -Medium Earth orbit (MEO) – most MEO satellites are at an altitude of 20, 000 km, and time for one orbit is 12 hours. Geostationary orbit (GEO) – 36, 000 km above the Earth. Time for one orbit is 24 hours.

Detailed explanation-4: -Satellites in this orbit travel at a speed of around 7.8 km per second; at this speed, a satellite takes approximately 90 minutes to circle Earth, meaning the ISS travels around Earth about 16 times a day.

Detailed explanation-5: -Satellite that goes around the earth once every 24 hours is called a geosynchronous satellite. If a geosynchronous satellite is in an equatorial orbit, its position appears stationary with respect to aground station, and it is known as a geostationary satellite.
