Toying with the new mercury models, I spot a odd issue with albedo. I have two objects not so far one from the other, both have the same albdo (0.08), both have components (but this should not change the final albedo) but within Celestia one stay visible much longer than the other depending on the distance. And not the good one, I guess the nearest from the observer should be the one visible, but no, it's the contrary...

What could explain such behavior?

The apparent brightness is a factor of the size of the objects as well as the albedo: a larger object simply reflects more light. Might this be the cause of what you're observing?

Ok that's must be the cause! I didn't knew albedo wasn't only a question of ssc definition... Celestia is really smart! Congrats!
Tx for the solution!
See you later for another noobish question!
