TRAPPIST-1 System by Cirax (UPDATE2)

05 May 2017 03:24

TRAPPIST-1 SYSTEM BY CIRAX

New version, full list of changes in my last post.

This are my procedural planets for the TRAPPIST-1 Star.  Four of them lay in the habitable zone (maybe more).

I focused the design in real data from Updated Masses for the TRAPPIST-1 Planets astronomical article April 2017.  In it the estimated mean densities of the planets reveal that the three closest planets are rocky while the rest are near the density of the water making them oceanic or ice worlds.

To add some variety to the oceanic worlds (not just a covered oceanic plain and boring world) I changed the size of the ice layer a some minor differences.

You can download it from here (20/8/2017 version):

To install just copy "TRAPPIST-1 Cirax.pak" inside the addons folder.  Don't forget to rename the extension .pak to something else if you have another mod of the TRAPPIST-1 system.


TRAPPIST-1 b

The closest planet to its sun is heavily affected by the tidal effect from the star making it some kind of hot Io.  It's a volcanic world with few craters and a young surface.  I added in the update a dark lava surface making it IMO a less boring planet.

TRAPPIST-1 c

This planet is still too close to the sun and due it's estimated mass, (1.63 times the Earth mass) which allow it to sustain a great atmosphere, I supposed is a Venusian world.

In the design I wanted to reflect that in this kind of cloud covered worlds the surface is dark due the fact the clouds reflect most of the light that would come to the surface, so I added another dark cloud layer under the bright one (to add a cloudy effect), darkened a lot the atmosphere but also making it less opaque.

Resuming, from the space the planet looks like Venus (a bight world) but if you land the surface and the sky is dark and the atmosphere is more transparent.

TRAPPIST-1 d

This rocky world stays close to the habitable zone, the central part of the planet is hot and devoid of any liquid water but in the terminator zone the temperatures are warmer allowing the presence of liquid water.  In that zone I placed a big sea and some big lakes and rivers.

TRAPPIST-1 e

This covered water world has a floating ice layer over it in the nocturnal face. The warm water of the surface coming from the tropics melts part of the ice breaking into the dark side of the globe.

TRAPPIST-1 f

Stil not cold enough to sustain a dense ice layer, Trappist-f has some ice swamps, lakes made when big asteroids broke the ice and rivers where different plates crush together..

TRAPPIST-1 g

It has a dense crust of ice except in the latitudes where the red sun is still enough powerful to melt it and break some parts of the polar cap into icebergs where they float over it until the sun also shrikes them and finally they melt totally.

TRAPPIST-1 h

The last planet (right now) of TRAPPIST-1 is just an iceworld. There is no liquid water in the surface, it's crossed by multiple cracks and has some craters.  Under the ice layer it could be a liquid water ocean warmed by the hotter mantle.

That's all, and sorry for my "barbarian" english :)

I downloaded this, and this mod is really awesome. Here's some photos I took of the planets:

TRAPPIST-1 System by Cirax (UPDATE2)

20 Aug 2017 11:03

Hi all, a new version for the system, here is the full list of changes: 

UPDATE2

Changes from the last version
:

--Trappist-1 b: Now has some less volcanoes and less active so I can avoid errors and the artificial grid effect in the distribution of volcanoes (with old value there was a couple of "black hole" errors in the procedural texture generation).


--Trappist-1 c: Temperature of the volcanoes decreased so they are a lot of harder to see from the night side.


--Trappist-1 d: Decreased temperature for volcanoes for the same reason as c.


--Trappist-1 e:
-Changed atmosphere model, it's also more opaque for the stars if you land in the surface, but still transparent looking it from the space.
-Some more clouds.


--Trappist-1 f:
-The swamp and rivers looking of f is now the one of the old trappist-1 g but with a bigger ocean.
-Changed ocean colour.
-Changed atmosphere like in e.


--Trappist-1 g:
-The icebergs sea looking of the old trappist-1 f replaces the old one.  There no rivers or swamps.
-The sea is some bigger to avoid the effect of a vertical cliff between the sea and the polar cap.
-Changed ocean colour.
-Changed atmosphere like in e.


--Trappist-1 h: Decreased brightness to a half.
