The formula for the force of attraction (F) between two bodies is:

Formula for gravity

- where -

M and m are the masses of the bodies in kilograms

r is the distance in metres between the centres of mass of the bodies

G is the Universal Gravitational Constant of about 6·67 × 10-11 Nm2/kg2*

(That's about 0.0000000000667 newton metres2 per kilogram2.)
