Hello.
I was just wondering if anyone could tell me more about the accuracy of celestia. I have two pet projects which I would like to accomplish and I wish to learn to use celestia for some of the research involved. First, I wish to find a habitable planet, somewhere in this galaxy preferably, and calculate it's logistics accurately. secondly, I would like to use celestia to calculate the time of the next likely earth impact of a climate-impacting size object. any advice from the pros? drop me a line at whytwzrd@yahoo.com
