Hi there, I wonder if it is possible to improve the lighting a bit more, Just so when there is a large surface area which caste light on a small one, the surface of the object should be more lighted.
Here's what I mean by that. So I put Jupiter in an orbit which almost always collide with the Sun.

It seems that the Lighting model you are using came from the centre of the Sun as single light source instead of being the sun using all of it's surface.
