Orbital velocity formula calculator

Orbital velocity formula calculator allows you to calculate orbital velocity of an object, at which it move to orbit of a planet in the solar system, or other massive body with defined mass and radius.

Select a planet or enter mass and radius

Orbital velocity of Earth
Orbital velocity (first cosmic velocity) is the minimum velocity, required to object, like artificial satellite, to keep it in orbit of planet.
where M - mass of the planet, R - radius of the planet, G - Universal Gravitational Constant = 6.67408 x 10-11Н*м2/kg2
