Anyone have info on it?

I've seen the wookieepedia article, but that doesn't give me everything I need to know about it, like for instance, its Orbital Metrics (day duration and year duration), the population, etc...

The wookieepedia page does a good job summarizing all the relevant info. You might glean more abotu the place's history by reading through the various battles, but since the game is really the only source for the planet, you can kind of make up whatever is useful as a GM to fill in the gaps.
