You've probably heard about the latest discovery by Mike Brown's team at Caltech.

If not, check it out:
JPL's press release: http://www.jpl.nasa.gov/media/072905/
Discoverer's Web site: http://www.gps.caltech.edu/~mbrown/
New Scientist article: http://www.newscientist.com/article.ns?id=dn7763

Here is some code to add to your 'extras' folder. Copy the code and paste it at the end of your 'outersys.ssc' file or create a new file and give it any name you like (as long as it has an ssc file extension).

Grant Hutchison has already added all the new planetoids to outersys.ssc

See his post here:
http://shatters.net/forum/viewtopic.php?t=7726

Or go directly to the file here:
http://cvs.sourceforge.net/viewcvs.py/celestia/celestia/data/outersys.ssc

Unlike Grant, I decided to call 2003 UB313 a 'planet' rather than an 'asteroid'. (As far as I'm concerned, the difference between planets and asteroids is arbitrary and arbitrarily we can call everything Pluto-sized or larger a 'planet'.)

hay thanks now i don't have to go and look it up

PS to all that are new it is very easy to add new things
just look at that bit of code it is simply a text discription

any new user can do it so go and give it a try

I have created a texture for the new planet. It is now available for download at the Celestia motherload. For more information, visit my topic about it in the addons forum. Later!
