askaniy looked at this spectra i found below and made a reasonable guese on color

as for co's venus, i don't know

Will the next release depict the evolution of the Solar System's planets besides the Continental Drift and Dying Solar System features (such as the formation of the Moon)?

No, now we have completely different priorities.

will you guys update the apophis (lightcurve) model with the 2018 study model? (posted a cmod conversion in a previous post)

I will look at this model later.

Art Blos wrote:I will look at this model later.

there are no incoded textures in my cmod conversion, so the model itself shouldn't need any modification, because there is already UV maps, and the oriantion is already fixed (some objs tend to have the mesh tilted on its side)

i did find a bit of a lighting issue on the bigger lobe, but i am not sure how to fix it
i think it happened when i was cleaning up the model

Great! Would you be so kind to share the pre-release exe file with us? You can use a password protected 7z file and send a PM with the password, to limit the release to the registered forum members.

If there is only 70% compatibility, that's a lot of work for add-on makers...

I'm not going to hide the installer for anyone. I just want to release something better than what I have now.

This is all our work.

Now about the exoplanets being rendered on the SSC files or about exoplanets period, the claimed planet around Barnard's star has been disputed after the radial velocity signal disappeared in the newer data:

Therefore in the next Celestia Origin update, have Barnard b and c removed.

This goes to show us how hard it technically is to find and confirm planets or anything of such anywhere outside our Solar System even with all the technology we have.
Planet hunting appears easy to us, but the scientists, telescopes and their data are constantly working hard and inspecting.

Added after 6 hours 38 minutes:
And about stars like Westerlund 1-26 (which's included in the top 10 largest stars file in the special stars folder), Westerlund 1-26's radius has been calculated to be 1165 to 1221 Sol radii whereas SIMBAD at its time corresponded the radius to 1530 to 1580 x Sol's based on based on effective temperatures of 3450 and 3660 K for M stars of such.

You know the whole exoplanets (confirmed and unconfirmed) along with the exostars of all types) files need updating since there are said to be many new ones discovered and the whole exoplanet database in Celestia Origin doesn't have them yet.
Not to mention the radii of some of them (like TOI-1338 b as well as HD 100546 b) for example need size and color updating (including TRES-2b and WASP-12 b) as well.

Certainly. But the possibility of updating exoplanets in the Origin...
- depends on Sirius desire wasting time for special preparation exoplanets so that we can update;
- depends on our current desire to do this, abandoning other equally important ideas.

And since there is neither one nor the other (moreover, the second follows from the first), use the original and do not clutter up the topic.

Each part and idea of CO would be updated at their individual times.
Other parts would also update at different times and might be worth the waits.

Since the exoplanets catalog is based off of Sirius's Exoplanet Catalog, whenever the exoplanets database is updated the Barnard's star planets will have been already removed.

I tried to download Celestia Origin v13 onto Celestia 1.7, but the features menu didn't show up.

We are already aware of the problem and even reported on another thread.

Which thread? By the way, why can't the evolution of the Solar System beyond the Continental Drift and Dying Solar System features be added? At least the formation of the Moon would be nice.

As I said to someone else in another thread:

What's the proper way to install Celestia Origin prior to v.14 on Celestia 1.7 and have the features menu show up? Which thread is it in?

We don't know yet.
