Also, a few thousand years after either goes supernova, will the shockwave itself, when it reaches Earth, have any effect on Earth or the rest of the solar system, or will it be too weak by then? This is an unfortunate myth that the media have propagated... A supernova would not actually have a sho...

I've been reading up on the asteroids of the Main Belt lately, and have discovered some resources that I think would be nice to see included in Celestia as add-ons or upgrades. They're mostly found at this site: http://home.comcast.net/~eliws/ceres/ This includes cool stuff like this new image of Ce...

It's a famous mathematical object in chaos theory, the origin of the well known "butterfly effect" celebrity (it looks like a butterfly). No, the "butterfly effect" refers to extreme sensitivity to initial conditions in any chaotic system. The term comes from the notion that a butterfly flapping it...

Thanks, that fixed it... though I still don't know what was wrong with it before.

Hi. I just downloaded the updated outersys.ssc file, the one that adds the name Eris for the former 2003 UB313. Or rather, I went here: http://celestia.cvs.sourceforge.net/celestia/celestia/data/outersys.ssc And then I hit "download" on the latest version, resulting in a bunch of text showing up ons...

Please feel free to edit the file to delete the asteroids you don't want to see, or to create a different file with just the ones you want. It's a plain text file, so your favorite editor should work fine. Hopefully it's obvious where the boundaries are for each entry: each one starts with a copy o...

I've created an Addon which displays 2140 of the more than 300,000 asteroids cataloged in "The Asteroid Orbital Elements Database" of Edward Bowell, which is described at ftp://ftp.lowell.edu/pub/elgb/astorb.html The Addon is available at http://www.lepp.cornell.edu/~seb/celestia/astorb.zip (290KB)...

Check out this thread: http://www.celestiaproject.net/forum/viewtopic.php?t=9412 I created a tiny addon (5k) that adds the nine missing main-belt asteroids that are 250 km or larger in size. ... It probably doesn't have the particular asteroids you are after but it's a start. It's a very good start...

In principle I could use the program that I used to translate the MPC's smaller, specialized minor-planets files to translate their full database, which now lists 299,673 bodies. (Not right now: the program's at home and I'm not.) Thanks, but I don't think I need that many. I know my desktop comput...

An addon with over 200,000 of the known asteroids is available on the MotherLode at http://www.celestiamotherlode.net/catalog/show_addon_details.php?addon_id=785 A smaller one is there, too. :) Those are the add-ons I mentioned above. They're useless to me because they don't catalog the asteroids b...

Hi -- new forum member here, though I've been using Celestia for some time. I've been working on a novel set in the Main Asteroid Belt, and though Celestia has helped me with the orbits of the top few Main Belt asteroids, it only had a very few of them and wasn't helpful with the rest. So I went loo...
