I think a planetary nebula. Sometimes they look oversized in Celestia according to the add-on .

But this one looks very big. Weird...

Thread bump: some water-rich Jovians and a bunch of brand-new planets from latest SuperWASP set.

- Water Jovian HD 99109 b. Accomplishing a request.





- Pi Mensae, massive planet within snowline. Assuming great water amounts, but I'm planning a new version, more cloudy and ammonia-rich. Assuming the same radius of Jupiter, mean density around 13.7 g/cc. Remarkably similar to a brown dwarf, rather a planet.



- WASP-29 b: hot-Saturn or "dwarf-hot-Saturn", as you like.





- WASP-33 b: first transiting planet around an A-type star.

I bet few know about this one: V442 Cassiopeiae and "Trojan" planet. Quite a "menage-a-trois", with Algol-type eclipsing binary and epistellar planet in L4 point (individual orbits underlined).

That planet doesn't look like it is anywhere near the Trojan point - the Trojan point should be at the vertex of an equilateral triangle in the plane of the binary, with the two stars occupying the other two vertices. It also doesn't look like the stars are at opposite sides of their mutual orbit?

Nevertheless I would have thought this configuration would be highly unstable, unless the mass ratio between the two stars is extreme?

Personally neither I do reckon such a kind of system to be likely.
Just meant to "revive" this system after viewing this page.
Just for fun.

I'd like to hear also some feedback about GJ 667 C and Nemesis.

Thread bump: revisiting some old and new exoplanetary systems.

- Super-Earth Gliese 667 Cb. Binary in background.



- Nemesis: the Solar System lurker...



- Revisiting Upsilon Andromedae System. I refuse to name them "Dinky", "Twopiter" and "Fourpiter". I prefer classical names Laughing



And also a putative moon around Ups And d.




- And even Rho1 Cancri.

Nice work on the gas giant textures. Perhaps try generating your own ring textures, those all look suspiciously Saturn-like.

Here I have used Saturn-like indeed. Other gas giants in "my stock" have different ring systems.

Generous thread bump. Planetary systems with giant star. Each star is depicted roughly 1 AUs away.

HD 104958 (G9III) Cam




11 Ursae Minoris (K4III)




HD 32518 (K1III) Cam




HD 13189 (K3II) Tri



14 Andromedae (G9III)



81 Ceti (G5III)




18 Delphini (G6III)




Xi Aquilae (G9III)




HD 3346 (K5III) And* brown dwarf around the most massive giant, so far detected.




Finally a system waiting for confirmation: CoRoT 102660283 (I tentatively call "Corot-Exo-X1"). SpT= K3III, Mon.
Includes a 23.4 Mj brown dwarf around a K3III giant.

@Edasich,

If you want, I'll trade you some ring textures for some gas giant textures

After a long series of real extrasolar planets or unconfirmed/unpublished exoplanet candidates, I wish to break the habit in this thread bump: putative rocky planets around nearby stars. Something new.
There is also something real within (as GJ 433 b) and something likely.

Sure I won't ever exceed John M. Dollan's magnificient rocky worlds beauty, but I'd like to share these works. They shall feature in a Science Fiction of my own. I hope to have resized picture to comfortably viewable resolution.


- Alpha Centauri A - 3rd of a 3 planets system and the least massive. Twice the mass of Mars and within habitable zone.




- Alpha Centauri B - 2nd of a 4 planets system. Venus-sized, in the inner edge of HZ. Hot oceans and deserts, halfway between Venus and the Earth. Geologically Active too.




- Epsilon Indi - 3rd of a multplanets system. Earth-like, noticed the face-shaped island? A Cydonia analog, land feature left by alien civilizations? Who knows...




- Alpha Mensae - 4th planet, icy and arid planet with thrice the mass of Mars.



- Epsilon Eridani - an inner rocky planet, primaeval and active. A future Earth-kin?




- Gliese 433 b* - the only real planet of the batch. A hot super-Earth around a M dwarf.




To be continued.

Yours are certainly better than mine. Here's my best effort so far at a hot Super-earth... this one being Gliese 581 e (with the background body being, of course, b).

Well, you're on the good way. Keep up the good job.


A bizzarre idea. A young rocky rogue planet in Chamaeleon Dark Cloud. In the neighbours of multiple system DX Cha. How about?

Interesting. I wonder how detectable young rogue planets are in the infrared...

Very very very difficult, with current instrumentation.

Midsummer thread bump
A bunch of fictional worlds orbiting (real) dim stars, M dwarfs included.

70 Ophiuchi A - gas giant + cold Earth-like moon




70 Ophiuchi B - another world supposed to orbit a gas giant, but quite colder, with a whole circumequatorial ocean frozen.




AD Leonis - well-known M dwarf primary target for Earth-sized worlds, but not like home, according to me.




Lacaille 9352 - with a perpetual ice age world as in stereotypical tidally locked M-dwarf Earths.








Enjoy and see you next thread bump. Wink

HD 10180 and the Magnificent Seven Very Happy Laughing

Had to take two different snapshots, or else 7 planets were awkwardly displayed





Plus a putative Earth-like planet within.

I'd like to make a thread bump, since long time this topic is resting.
But I have not seen your impressions about HD 10180 system rendering Razz

Some epistellar jovians of HATNet, in alphanumerical order.


HAT-P-7 b - one of the most studied. Cool




HAT-P-15b - "that with heart of stone". Laughing
Likely to yield a massive rocky core (up to 50-100 Earth masses)




HAT-P-20 b - massive hot Jupiter, the heavy one of the batch. Rolling Eyes

Like your planets.

Yeah, the ring system is Saturn-like. XD

Might also try:
- Neptune-like = faint, thin, and unevenly distributed.
- Uranus-like = faint, thin.
- clumpy-like.
- bannanna-like, where it's not a complete circle.
- thick, like Saturn but has multiple gaps and is wider.

I'm going to have to applaud your work Edasich. Your textures are masterful, each unique, realistic, and pleasing to the eye. It seems a shame to see so few of these put on the Motherlode.
If you don't mind, I'd like to request some more of the fictional terrestrial planets.
