What are the different orbits around the Earth?
Depending on their respective altitudes from Earth’s surface, there are four main types of orbits around Earth, namely Low Earth Orbit or LEO (the International Space Station is in this orbit), medium Earth Orbit or MEO (home to GPS satellites), geostationary orbit, and High Earth Orbit or HEO (contains only a handful of satellites, like NASA ’s
What is SSO orbit?
A Sun-synchronous orbit (SSO, also called a heliosynchronous orbit) is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet’s surface at the same local mean solar time.
What is the orbital velocity of Earth?
Earth’s orbital speed averages 29.78 km/s (107,208 km/h; 66,616 mph), which is fast enough to cover the planet’s diameter in 7 minutes and the distance to the Moon in 4 hours. From a vantage point above the north pole of either the Sun or Earth, Earth would appear to revolve in a counterclockwise direction around the Sun.
