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.

It doesn't work for me on Windows, though it obviously worked at one time since the old Ran addon (developed on macOS/1.5.0, I think) has InfoURLs pointing to local html files and celx scripts.

Why is EBLM J0555-57 Ab defined as an F-type star instead of an M-type star?

Kepler-58 e is confirmed by Valizadegan et al. 2023.

And such "imperfections" are noticed by multiple people, pretty much anyone who uses it often and especially pans the view while on the surface. There's no evidence that this is the case. You were the first person to mention it, and before you did I hadn't noticed and assumed the model wa...

I didn't really "direct you here", I just said this is the source of the models, but this is definitely a more appropriate place for the discussion. You'll have to wait for a response from cubic, but I don't think there's much need to modify the mesh to remove small imperfections only noti...

Actually, more recent research suggests that 55 Cancri e does not have a thick atmosphere. With a temperature of over 3,000 K , it also seems likely that the planet would be completely molten, though it might be more realistic for it to be non-emissive, with reflected light from the star being domin...

SSB = Solar System Barycenter

This name as an object must be defined in a file.

nearstars.stc, line 41

ReferencePoint "Earth" "Earth_bary" Earth_bary orbits the Sun, so for Celestia to find it this needs to be: ReferencePoint "Earth" "Sol/Earth_bary" but that's still not modifying Earth, just adding a reference point called "Earth". Looking at the SP...

what is "SSB" ?

Solar System Barycenter.

Site will be unavailable for a while since Apr, 14 - most people can't access the forum currently.

GJ 1214 Orkaria & Enaiposha GJ 1214 is a red dwarf star 47.8 light-years away in the constellation Ophiuchus. Its one known planet was the second super-Earth/sub-Neptune observed to transit its host star. The planet has a low density, indicating a volatile-rich composition, and recent observati...

Since this thread has been used in the past for new Solar System discoveries... Saturn now has well over 100 known moons.

(Also, Quaoar has two rings, at least one of which has been added to Origin; there's already a released addon that updates Quaoar.)

Kepler-138 Low-mass, low-density worlds Kepler-138, also known as KOI-314, is a red dwarf star about 219 light-years away in the constellation Lyra, which hosts four known planets. Kepler-138 c & d are both about 1.5 times the size of Earth; they were originally estimated to have very different...
