What is Earth Orbit?

An orbit is a regular, repeating path one object in space moves around another object. An object inside orbit is called a satellite. Like all planets in our solar system, the earth also has its own orbit and it is slightly oval shape. Earth is also one of the satellite as it moves around the sun.

Formulas for calculating Orbital Speed and Period of Earth's Orbit

Earth and other planets orbit the sun in circles. Finding a satellite's orbital speed and period is significantly easier in circular orbits. Earth's satellites orbit the earth at a definite height for a constant period of time.

Now, we will look into the formulas for calculating orbital speed and the period of the earth's orbit.

Orbital Speed of Earth's Orbit Formula

Orbital Speed

Where,

  • G = Earth's gravitational constant.
  • RE = Earth's radius.
  • ME = Earth's mass.
  • h = Satillite perpendicular distance.

Orbital Period of Earth's Orbit Formula

Orbital Period

Where,

  • G = Earth's gravitational constant.
  • RE = Earth's radius.
  • ME = Earth's mass.
  • h = Perpendicular distance of the satellite.
