The Mass from Speed and Separation calculator computes the mass of the object (e.g. planet) based on the orbital speed (v), the separation (R) and the universal gravity constant (G).

INSTRUCTIONS: Choose the preferred units and enter the following:

• (V) This is the orbital velocity.
• (R)  This is the separation distance.

Mass (M):  The calculator returns the mass of the object in Earth Masses (multiples of the mass of the Earth).    However, this can be automatically converted to other mass units (e.g. kilograms) via the pull-down menu.
