## Frequently Asked Questions

What is a synchronous satellite orbit?

A satellite in a synchronous orbit that is both equatorial and circular will appear to be suspended motionless above a point on the orbited planet's equator. For synchronous satellites orbiting Earth, this is also known as a geostationary orbit.

How do you calculate the radius of a geosynchronous orbit?

R = Radius of the planet The geosynchronous orbit (synchronous orbit of the Earth) is at an altitude of 35,796 km (≈ 36,000 km) and has a semi-major axis of 42,167 km. Excel formula used in this table to calculate the altitude of the satellite in synchronous orbit of the planet: = ((((G*M*T^2)/ (4*PI ()^2))^ (1/3))-R*1000)/1000

What is the relationship between orbit radius and period?

When a satellite travels in a geosynchronous orbit around the Earth, it needs to travel at a certain orbiting radius and period to maintain this orbit. Because the radius and period are related, you can use physics to calculate one if you know the other.

How to calculate the semi-major axis of the synchronous orbit?

Excel formula used to calculate the semi-major axis of the synchronous orbit of the planet: = ((((G*M*T^2)/ (4*PI ()^2))^ (1/3)))/1000 Table: synchronous orbits of the planets and moons of planets. 1997 © Astronoo.com − Astronomy, Astrophysics, Evolution and Earth science.
