What are the sources of light that we see coming from the planets?
I'm sure most of the light originates at the sun and reflects off the planets, but could there be other sources?
Couldn't a few photons be coming from reflected starlight? How about volcanoes? How about the hot glowing clouds or Venus or Jupiter?
....OF Venus or Jupiter?

There might be *very little* light coming from the stars... but, take the sun away, and I doubt we'd be able to detect any of the other planets.
Jupiter does radiate more energy than it receives from the sun (the only planet to do so), but none of it is in the visible light range.

No, the planets are not "suns" themselves, they have no light of their own---The sun reflects off of them, so we can see them.
