A hot Jupiter exoplanet is 8×10^9 m from its star, and has a radius of 70000 km. If it reflects 10% of the light that falls on it, how much fainter is it than the star, as viewed from the Earth?

What is the ratio of star flux to planet flux (i.e. flux from star divided by flux from planet) as observed from the Earth?
