Source is this: https://web.archive.org/web/20120317203801/http://www.astro.princeton.edu/~dsp/PrincetonSite/Home_files/darkest_world.pdf It states even with a commonly understandable albedo of 0.0136 (1.36%), the best fit model measurement shows an albedo of 0.0004 (0.04%).

Yup and it's worth the patience and effort to get it all up to date. Here's TRES-2 Ab with the albedo at 0.0136 (1.36%) which's what it's also often recognized at being and many sources also state it's albedo's 0.0136. Somehow many state it's 0.0136 and others state it's 0.0004 (0.04%) which's incre...

Yeah and they might also need to be part of such a project as well.

Well we need to keep improving technology to see what such stuff out there really looks like and that's pretty much a whole new level of telescopic exploration. Another misconception of exoplanets is about highly "habitable" planets orbiting red dwarfs when they're tidally locked and numer...

Yup and I even had to change the radius of HD 100546 b on Art Blos' Celestia Origin to its most accepted value, add a night texture (sudarsky-class_4-night.dds) a red color to it and change the Mie colors to match the most accepted appearance. It's ~20X Jupiter's mass (which matches that of a typica...

Now Art Blos' Celestia Origin has great exoplanet textures too along with atmospheres on such planets in the exoplanets file (which's used for the folder of the same name placed in the extras). https://celestia.space/forum/viewtopic.php?f=23&t=21114 I guess this's good for users without Celestia...

It's all I had to say at this moment since there's nothing else to say about what I said before. Exoplanets are extremely hard to find as they're so far away and technology is limited and even the transiting ones are hard to detect as the planets take up very small fractions of the stars, blocking o...

It shows us that even to this day with all our technology, we never really know what's out there.

Yup. That's among the things on CO that should be kept up to date the most often.

Alpha Centauri Bb was disputed fairly recently. Remember?
Barnard's Star b was also disputed (in fact in 2021).

In 2021, the radial velocity signal vanished since we got newer data about the star, proving the so-called planet doesn't exist after all: https://www.forbes.com/sites/brucedorminey/2021/05/18/astronomers-nix-idea-of-super-earth-around-barnards-star/?sh=79891a41842a

How about a lack of things such as the life cycle of stars and nebulae evolution along with pm (proper motion) and plate tectonics on terrestrial bodies like Earth for example.
Plus no tides or anything related and no universe expansion.

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...

Celestia Origin needs some massive updating on some files, like exoplanets and stars.

Well remember since it's part of a circumbinary star system containing 1 F8 main sequence star (which's white) and 1 red dwarf star, the white and red combo lead to a pink reflection. Yet the cloud map is technically multicolored from all the certain chemicals interactions of its weather. Hydrogen, ...

Now the artistic impressions apparently accounted for the fact that the planet orbits 2 stars.
1 F8 (main sequence) star and 1 M (red dwarf) star.
F-stars are whitish and M-stars are reddish.
Yet that's pretty much how the planet looks in the artistic impressions.

FYI for those using Celestia Origin, each star in this addon has to have the mono texture in order to work on the meshes. Default stars on Celestia Origin use VT textures which meshes don't support. A-stars in this addon would say: Texture "star-a-mono.dds" B-stars in this addon would say:...

Yup, and we can't make an addon where an object classified as a planet, Moon or spacecraft would have a spectral type or apparent magnitude like a star would.
Celestia wouldn't render the planet, moon or spacecraft like that.

As you can see, its Radius size is at an impossible 3900 Rsun! If I remember, the actual largest discovered star, UY Scuti, only has a radi of 1800+Rsun. So, this one had to be the wrong size for the star. UY Scuti's currently estimated to be 1708 Rsun actually, which's a bit smaller than 1800, tho...

Yeah, and the point is in reality, it would be impossible for a star to look like a terrestrial planet unless the mass is reduced and density matches that of a terrestrial. Yet in reality, we can't turn a star into a terrestrial planet and not change its mass, size or density. Yet in reality we don'...
