Use Kepler's third law to find the planet's average distance (semimajor axis) from its star. (Hint: Because the mass of the star is about the same as the mass of our Sun, you can use Kepler's third law in its original form, p2)

Explanation: The planet average distance = 42300km

Kepler's 3rd Law also known as the Harmonic Law states that;

for each planet orbitting the sun, its side real period squared divided by the cube of the semi-major axis of the orbit is a constant.

A planet, mass m, orbits the sun, mass M, in a circle of radius r and a period t. The net force on the planet is a centripetal force, and is caused the force of gravity between the sun and the planet.
