The Planet's Mass from Acceleration and Radius calculator computes the mass of planet or moon based on the radius (r), acceleration due to gravity on the surface (a) and the universal gravitational constant (G).

INSTRUCTIONS: Choose the preferred units and enter the following:

  • (r)  This is the radius of the planet.
  • (a)  This is the acceleration due to gravity on the surface of the planet.

Planetary Mass (M): The calculator returns the mass (M) in kilograms.  However, this can be automatically converted into other mass units via the pull-down menu including the following:

  • Earth Masses
  • Jupiter Masses
  • Solar Masses

The Math / Science

Compute the mass of a planet given the acceleration at the surface and the radius of the planet.
