Proxima Centauri: Part One now available for download

[kikinho]

Will you make at least one planet with complex life, like Earth. Or could has complex life but with another condition, like a planet with ammonia oceans with a high atmosphere pressure having nitrogen, methane, ammonia, some nitrogen dioxide and hidrogen, with a surface rich in phosphorous and having heavy or light elements in it. The color of this kind of atmosphere is brown I think, with white or brown clouds.
Because of the red light of Proxima Centauri, the plants shold look like: violet, pink, blue, or even bluish green ( aquamarine color ).
If the planet has an atmosphere thicker than Earth, is shold be bigger than Earth. Ultraviolet radiation is not a problem because of the low radiation that red dwarf stars produce.

Or create a planet with a completely different kind of biosphere or even the same as Earth.

Or there's life in moons, like on what scientists think about Europa moon of Jupiter?

[Michael Kilderry]

There are no real Earth-like planets orbiting Proxima Centauri in my addon because it is the wrong star for it, but there are quite a few worlds around that have some sort of life:

Asjuill (moon of Kretus) - A Europa like moon, some small areas on the surface are seasonally liquid water lakes, as well as underground deposits of water like what is said to be under Europa.

Sulcia (another moon of Kretus) - An electrical type moon with huge circular lifeforms that are powered by the light of Proxima Centauri. They are made of gas and like rainbows, dissapear when you get close to them.

Unterra A tidelocked world, water exists on liquid form on the terminator of this planet where algae lifeforms could possibly evolve.

Epi, Kretus, Demeter, Poseidon and Aurora Primitive lifeforms could possibly exist in the atmosphere of these gaseous planets in the less turbulent regions.

Carusis and Ursae (moons of Poseidon) These worlds both have lifeforms similar to that of Sulcia.

Magellan and Tritonia (moons of Poseidon) These worlds both have liquid oceans on their surfaces (but not of water) and both are tectonically active and have clouds and weather. These are like Proxima's equivalent to Titan in our solar system.

There are even more worlds around Proxima that could be home to some sort of a living species, including ones I haven't made yet.

I have enjoyed visiting your worlds, Michael; they are unusual, but spectacular. You have invented some interesting physical conditions on each world as well- this is good, because when we do eventuallystart imaging distant exoplanets, I expect them to be both varied and surprising in many cases.
I have a couple of questions, though-
you say Demeter is oblate because of starlight, as well as because of its rotation- how would that work?

And how did its neptune-sized moon Starlight manage to avoid becoming a gas giant with a massive atmosphere? A neptune-sized terrestrial would have a gravity many times Earth's; it would retain any hydrogen it was created with, and would attract more hydrogen from the protoplanetary cloud until it was at least as big as Demeter. Then you would have a double gas giant.

...you say Demeter is oblate because of starlight, as well as because of its rotation- how would that work?

This works because Starlight moves in the same direction to Demeter's rotation, and since Starlight is huge and gravitationally powerful and Demeter is spinning itself flat, these forces work together to make a very oblate gas giant. Although I'm not sure if this could happen in a real universe situation, but it is an interesting concept.

And how did its neptune-sized moon Starlight manage to avoid becoming a gas giant with a massive atmosphere? A neptune-sized terrestrial would have a gravity many times Earth's; it would retain any hydrogen it was created with, and would attract more hydrogen from the protoplanetary cloud until it was at least as big as Demeter. Then you would have a double gas giant.

This could be explained by Starlight and the other Demeterian moon Kankymede, being flicked out of Proxima's inner system (containing denser materials to make planets instead of the lighter atmospheric stuff) and then being captured into being permanent moons of Demeter.

These two moons supposedly were flicked out very fast, Kankymede's clouds froze so fast with the temperature change that they turned into frost still in their cloudy patterns. Again, I'm not sure if this is possible in a realistic universe.

Here is another picture, this is of Tritonia as anticipated.



This is another electrical type planet. The oceans on the surface are made of a liquid magnetic metal, which electrical lifeforms life in, the magnetic forces between the creatures and the liquid create uneven bulges and dents in the liquid's surface, so in many places the sea floor is exposed and other places have very deep oceans and submerged continents.

I have accidentally made the clouds far too high when I first created this world, but I've kept it in the above picture because I liked the effect, I would like to hear other people's opinions on the cloud height issue though.

And here is Aurora and it's moon Australis (shown in front). I am currently working on these two:



Next world in order to be pictured: Borealis, the 2nd moon of Aurora

Just wanted to point out that Aurora Australis and Aurora Borealis are stars. Smells like a major relationship to me...

[Michael Kilderry]

I came up with the name Aurora because of the big flares that come from Proxima, and since this creates auroras on planets, I thought Aurora would be a suitable name for one of Proxima's planets. Although at planet Aurora's distance from Proxima the solar flares wouldn't have much of an effect.

The names for the first two moons com from the names of the two types of auroras that appear on Earth. Aurora Australis, which occurs near the south pole, and Aurora Borealis, which occurs near the north pole.

There will be more moons to orbit Aurora though, what do you think of the names Camelopardus, Capricornus and Bacchus for the other planned moons of Aurora?

More images of the Aurora System, still a work in progress...





After the Aurora System, I have only two more worlds (a planet and one moon) to make before this addon will be finally finished. If you have any further comments, please post them.

Good work! This add-on will be finished in few days? I'm anxious to use it in my computer. But...
Later when you have finished your add-on, what will be the next star? Or you'll create a new star for your next system?
But anyway Proxima Centaury system pictures are great. Congratulations!

[Michael Kilderry]

Good work! This add-on will be finished in few days? I'm anxious to use it in my computer. But...

I'm afraid the addon will take more than a few days to complete. Although I have made all the planets and moons I wanted to include, I still need to check some things and then I have to get the addon sorted and ready, with a readme file, put it in a zip file and upload it to the Motherlode, and then it still may take a couple of days for it to make the creators directory, depends on how busy the Motherlode staff are.

So not completely ready yet, sorry if I was misleading.

Later when you have finished your add-on, what will be the next star? Or you'll create a new star for your next system?
But anyway Proxima Centaury system pictures are great. Congratulations!

I have already made a start on my next addon. It will be another solar system as suspected, this time around Rigel Kentaurus B. I know at least two other Celestia addons are solar systems based around this star, but I had ideas for a system around this star before I even knew about other people's Celestia addons.

The first planet is called Vulcano, as for the appearance of this planet the name is self-explanatory. I'll make a new thread for this next addon when I'm ready to show images and promote it. It might not have as many planets or moons as Lera or Proxima though, but it will probably be of better quality due to my increasing knowledge of addon creation.

The textures are good.

[Beowulf01]

I really do like the colors...

[kikinho]

The Lera system gave me the idea to create an eletrical planet in my system and double giants. Now the Proxima Centauty system screenshots gave me other ideas to create my own system. I'm doing a big system based on a K star.

That's great Kikinho, keep up the good work!

Do you like the colour of the moon Lunarcticus? I was going to change the green haze to more of a purpley colour, it looks a bit too bright to me at the moment.

[Beowulf01]

maybe soften the color a little bit....
other wise they look nice.

That's what I'm thinking about doing, but the only planet or moon that I want to change the colour of in a major way is Lunarcticus, it hasn't turn out how I planned at all.

But anyway, here are some more images of some moons of Aurora with some bump maps and specular textures which I have added to them:

First up: Australis with planet Aurora in the background.


Here's another: Australis in closeup by itself.


With Borealis in the foreground:


Borealis with the Magellanic clouds in the background:
