An exoplanet of mass 1.36x10^26 kg is orbiting a star of mass 3.2x10^31 kg at a distance of 1 AU. What is the magnitude of the gravitational force between the two?

We use Newtons equation for gravitational force. F=GMm/r².1 AU is the mean distance at which the Earth orbits the Sun, taken to be: 1.49x10¹¹ m.Substituting in the numbers we find the magnitude of the force to be: 1.3075x10²⁵ Newtons
