Can Celestia list the mass of objects?

Post #1by adi11235 » 10.01.2007, 11:49

The question is in the subject line.


Basically, I'd like to compare the size of astronomical bodies, but radius in itself doesn't tell me how massive a body is. The star class gives me an idea, but I'm wondering if I can get a better approximation.

Thanks.

Celestia only lists data by default that exist in form of direct scientific results. The mass is NOT such a quantity, since it obviously depends on various assumptions besides possible measurements. But using the Lua overlay facility, one may easily display more/other parameters as well on a custom basis.

The Lua overlay facility is used in Vincent's Lua Edu tools to do this and many other things. You might want to give them a try.

They're a work-in-progress, though, and do have a few bugs. Be sure to report whatever problems you encounter.

Selden,

Thanks for mentionning the Lua Tools. Just a minor rectification, though :
All known bugs have been fixed in the latest beta version, and I'm about to release v0.1 very soon. I'll start a new thread for the release of v0.1.

Vincent,
If all known bugs have been fixed then wouldn't 1.0 be more appropriate than 0.1 as a release number? :lol: :twisted:

Well, I'm planning to integrate some other features, e.g. the modified version of Pointing Hubble, that I've removed because it's not currently working as expected (bugs ?). So, I'd like the 1.0 version to include all the features I'm currently working on...

Wikipedia seems to confirm the relevance of your comment, though :wink: :
