are you after texture or shading?
I’m supposing shading – in that case yeah, a lambert diffuse is not appropriate
for planets (and other stuff)
some more info here:

OrenNayar, TorranceCook, Architectural shader with the roughness parameter or
even an incidence (based on light direction – going into a bw gradient where
you move the midpoint) should all get you in the right direction.

Hey folks
I need a quick help. Is there any surface shader that creates a planet surface?
Cheers
