Celestia Forums

Wikibooks may be helpful though it's not edited much; you can also try this old guide. Really the best way to learn how to make Celestia addons is to look at how existing ones (like this) are set up.

This topic has come up again on Discord so here's a poll on it. Celestia currently uses the "moon" class for large moons (≥200 km radius) and "minormoon" for all other moons, regardless of what they orbit. This is based on Celestia Origin & Project Echoes conventions, and was...

There are two unconfirmed exoplanets orbiting Luyten 726-8; all are about the size of Jupiter. Even though they aren't confirmed, why not give them a try? http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2000AJ....119..906S&db_key=AST&high=38e0b7728707947 They probably are disproven ...

The discovery paper does call it "the smallest microlensing planet", but that's referring to the mass ratio with its host star; there are a few microlensing planets with smaller absolute masses, like this one. I've edited the Wikipedia article to make this more clear.

Teegarden's Star
Two temperate Earths and the nearest cold Earth

It's here! Along with addons for every other confirmed planetary system within 10 parsecs.

Tonight on arXiv: 2 new planets around Teegarden's Star using CARMENES GTO and Legacy-Plus Awaiting for that just because all sub-10 pc planets are done! Well, it took a few months and there's only one new planet, but here it is ! I'm working on updating/re-releasing some addons in the Nearby Exopl...

New name: 524522 Zoozve = 2002 VE68

I've checked Celestia Origin's entire catalog of minor planets for things that need to be updated. Minor planets with missing names and/or numbers ⋅  3708 Socus = 1974 FV1 ⋅  4035 Thestor = 1986 WD ⋅  4489 Dracius = 1988 AK ⋅  4715 Medesicaste = 1989 TS1 &sdot...

Releasing things I made and need to release... Here's a model for Bennu I converted for Celestia in September. Source is the first, highest-resolution model here . This can be used with Askaniy's shaded or albedo Bennu texture. I could release a full addon, but there are people working on adding ast...

This is a projection for use on planetarium domes. See this thread where it was implemented.

Did you UV map the model in Anim8or, as described in this tutorial ? Is the texture where Celestia can read it (i.e. in the "textures/medres" directory)? Your files should be set up like this: Celestia - extras - [addon directory] - [file defining object].ssc - models - [model].cmod - text...

Already existing addons for stars beyond the Local Group:

• NGC 55 by Gurren Lagann
• M 81 by ttcz
• NGC 300 by ttcz

That's not new, it's the same result you were saying is unreliable two years ago...

And this stuff about star sizes isn't really relevant to the original topic of this thread, which is over four years old.

1 AU is 149597870.7 km, searching Celestia's codebase confirms that this is the value used.

The celestia.mobi site is intended to be one central place for Celestia addons (as was the Motherlode when it was maintained). Trying to make another site with this purpose would likely make things more chaotic. I've tried to make things easier to find by making a list of addon threads and list of m...

For values in ssc files where the unit is years, 1 year is exactly 365.25 days. Celestia's date calculation is of course more accurate than this.

For the spacecraft's name, it can be safely simplified to "Psyche:2023-157A" only, since the asteroid has the numerical designation before it, so that could be left as "16 Psyche:Psyche (asteroid)". Celestia Origin has done this with its own version of the Psyche asteroid and th...

This was a bug with the "Points" star style on Intel graphics that has been fixed in more recent versions of Celestia. Try setting the star style to "Fuzzy Points", or using Celestia 1.7.0 which doesn't have this bug and has sound support (which was the only additional feature in...

I tried that. It doesn't work for me.
