Gliese 59 goes as HIP 7235 in Celestia.

Re: Asteroids for Celestia

Hello everyone. This is an updated version of the Neptune Trojans add-on I created earlier. Compared to the previous version, it has one additional Trojan (2012 UD185) and updated designations and names for a few of them.

(edit: the new asteroid is 2012 UD185, not 2012 UV177.)

Enjoy:

Re: Extrasolar Planets (updated catalogue)

That being said, I still plan on finishing up and releasing mine soon. Textures are a problem though, we should have a discussion on this. Change of plans. In the interest of not having two separate versions of what is essentially the same project, I'm not going to release my exoplanet catalogue af...

Re: New Celestia unified runtime database

So, I also proposed the opposite: adding _ at name beginning would prevent Greek replacement. I still think it would be simplest solution. Personally, I would go with this choice. It's not very clean-looking, but it keeps backwards compatibility. This is super important for a piece of software whos...

Re: Project "Celestia Origin", release dated April 30, 2019

Are the names based from the latest update of the GCVS Catalog: http://www.sai.msu.su/gcvs/gcvs/gcvs5/gcvs5.txt. ? The latest edition of the GCVS was on 2015 but its latest annotation was on April this year Indirectly. I actually extracted the names from SIMBAD, because I find that to be easier. Ho...

Re: Project "Celestia Origin", release dated April 30, 2019

4: I cannot suggest this for the next release because it might take a really long time but I'm currently working on improving the starnames.dat file by adding the Working Group of Star Names names given to stars by the IAU since 2016, names from Stellarium, members of the General Catalog of Variabl...

Hi Kilo_SSK, you should ask toutatis for that. He's our resident expert on making spacecraft add-ons.

I understand that. But these two threads are completely separate, so why was that one not turned into an announcement by itself? Why the merge?

Re: Populating WLM (and other galaxies) with REAL stars

Hi, I know I'm a bit late, but also very confused. I certainly remember a "Extrasolar, Stars and Exoplanets for Celestia" thread started by gironde. What happened to that thread?

Re: Extrasolar Planets (updated catalogue)

While it's not wholly accurate but you can use the SDSS Catalog as well, since so far, it's the most massive and comprehensive galaxy catalog. Mmm, can you clarify? The SDSS is a huge survey, with many data releases and resulting catalogues. And I couldn't find any of them have galaxy morphological...

Re: Extrasolar Planets (updated catalogue)

A galaxy catalog is needed, as well as stars within those galaxies, which LukeCEL has already started some time ago. My "stars within galaxies" add-ons are semi-fictional; they shouldn't really be in the main Celestia package. Sure, they represent real stars as accurately as possible. How...

Re: Extrasolar Planets (updated catalogue)

I line myself up with LukeCEL in the team of the "bit jealous people", because I was also working in my exoplanet catalog. You too? :eek: Funny how so many people were working independently of each other. That being said, I still plan on finishing up and releasing mine soon. Textures are ...

Re: Celestia 1.7.0 Development Thread

Thanks for the status update. Can I ask how much of these changes are backwards compatible? If possible, I'd like to do as little as possible with my star databases and cross indices. (Preferably nothing at all, since there are countless other stars.dat files out there). I don't know yet how Gaia na...

Re: Solar System Objects for Celestia

Oh, silly me, I think I remember seeing such a paper, but I didn't bother saving it.

Added after 5 minutes 49 seconds:
Is it this, by any chance? (Thomas et al. 2013) It has an incomplete map of Helene, as well as map-like diagrams of craters and flows.

I second this. Helene has a lot of really nice photos, but I haven't seen any textures of it so far.

Wow, this is really cool. Yours has a lot of advanced stuff like spin-orbit alignment, as well as well as stellar oblateness from v sin i.

Re: 55 Cancri

fyr02, do you happen to be using https://www.swift.psu.edu/secure/toop/convert.htm as the RA/Dec converter? If so, I recommend using http://www.astrouw.edu.pl/~jskowron/ra-dec/ instead, which is more flexible. It allows up to 4 decimal degrees for the arcseconds.
