Think of this thread as the inverse of the highest ESI challenge, where instead of finding a world with life like earth, find the most bizarre world that somehow supports life you can. The lower the ESI, the better.

The challenges I present to people who click on this thread is the following:

-Find the weirdest world that has life in terms of ESi and just plain strangeness. The world must have life on it.

-Find a sister world of any planets posted in this thread. For instance, try finding a world similar to Preta. Mainly to see just how exceptional worlds as peculiar as the one I have show cased really are.

-Try to describe the planet in some way.

Bonus:

-Must be organic life
-Can't be jovian or subglacial

================My Attempt=========

On my journeys in space. I encountered a world little more than a thousand kilometers in diameter, smaller than our moon yet capable of holding an atmosphere. This moon orbits a selena I should note. It is classified as a cold desert. I call the moon "Preta", mainly due to its ghostly appearance.





Here's my world. The world looks ghost-like, this is due to the bluish, yet thin atmosphere and the violet color of the alien plant life that dominates the planet. The world exhibits volcanism, which may be why the world holds an atmosphere in the first place. Also notice the size of the craters.



Here's the general information of the planet. Note the gravity and ESI.



From the surface the planet gives the impression of a endless meadow, however much the world's incredibly low gravity makes me imagine some really strange trees and jungles that sprawl above the plain. Life here would be able to jump incredibly high without much effort I imagine. The world's gravity being so weak, falling thousand feet wouldn't do much.

Planet ID: RS 8409-1792-7-1182125-712 5.1

Update:

Here's something I wrote about what the native society may be like. It also is just me trying some creative writing out and this world became a subject in it.

Desert worlds with life in this version are quite strange too.
This one is rotating around gas giant, it is a desert with gravity about 0.2 g, but the atmosphere is a bit thicker than Earth's, and it's heated up by tidal forces.

Code
Place    "Moon Temperate desert with life"
{
  Body    "HIP 14286 8.1"
  Parent    "HIP 14286 8"
  Pos  (-4.594666104290775e-010, 3.017378014114058e-012, -1.650206039524593e-010)

A low gravity world with a thick atmosphere?

I suspect the air on that planet probably is very different from earth's for sure. I lack much knowledge in chemistry currently, so I couldn't make any good speculations other than whatever air is there, it's probably thicker than nitrogen. Maybe this is a carbon moon?

I think I have found one of the strangest inhabited planets in the galaxy, perhaps even the whole universe. My hardware really sucks atm so I am unable to provide screenshots, but here are the details. Maybe someone with a better cpu can visit this eerie planet and put up some nice pictures.

The code for this planet is RS-8409-2706-7-599210-2531 2

This world is a large, cold gas giant deep within the core of the milkyway galaxy, coming in at at approximately 2.4 jupiter masses. It orbits the barycenter of a trinary system, two closely spaced red dwarfs orbited by one orange dwarf about .6 times the mass of Sol.

It's earth similarity index is 0.092

This planet is so far away from it's parent stars, that it takes roughly 7500 years to complete an orbit about them (orbital period of 7488 years!). With a semi major axis of 376.5 AU, this planet orbits it's parent stars at almost TEN TIMES the average distance of PLUTO from our sun.

Needless to say, this planet is extremely cold and dark with only two of it's parent stars visible, both appear simply as close, bright stars. The average temperature on the "surface" is a frigid -253 degrees celsius, just 20 degrees above the absolute zero.

This planet is almost as old as the universe, at 12.23 billion years old it is roughly 3 times the age of our earth. The life on this planet must be ancient in the extreme, it is complex and multicellular, and the planets bioshpere is classified as aerial. Though I can't even imagine the nature or formation of this life in such an extremely cold and alien environment, especially given it's other, even stranger qualities. It has an impressive clutch of 20 moons, the closest of which displays a dark, foreboding ring system.

The strangest feature of the planet however, especially considering it's large size and advanced age, is it's rotation rate. Completing a rotation around it's own axis in just under 8.5 hours! With a rotation rate of 8 hours 29 minutes and 41 seconds the planet has a large difference in effective gravity between the equator and the poles due to centrifugal forces. The average gravity across the surface is about 5.3g, and a person standing on the equator would experience about 14% less gravity than a person standing at the poles. Surprisingly however, the planet is not visibly oblate.

The planet is a dark muddled color, with green and brown bands barely distinguishable in the murky light. It features several large "eyes" or storm systems, which appear to be semi-permanent in nature. Being in the core of the galaxy, the night skies in are a sight to behold in the upper portions of the atmosphere, with a huge amount of visible stars and many visible large globular clusters at a distance of under 100 ly.

I'm totally violating the "no jovians" rule but this is by far the strangest planet I have ever found, even discounting the fact that it is inhabited. Due to it's extreme age and low temperature, I have dubbed this planet "Ymir".

Would love it if someone looked it up and posted a few screen shots for me smile the planet is disturbing, eerie, and utterly alien.

Hylozoist, there are several planets just like that in the nearby star systems... I think that should be a glitch of life funtions...

Does not work? It says object not found...

RS codes are put in through console I think. Searching for the star won't do the trick, let me find out how to do it real quick I'll post here so everyone who's doing the challenge can see.

Actually that's totally wrong, just confirmed you could do it. One of us must have gotten the code wrong.

Hi guys. First post!

4862 light years away from Earth, I have found a strange and beautiful planet. Similar to Preta, it is a small desert moon that nonetheless harbours life.



It is slightly larger in diameter than Preta and also exhibits none of the evidence of volcanic activity that the other planets thus so far found do, though it's ESI is past the 0.5 mark. Still, the most striking thing I found about the planet was just how close it orbits its parent at just 80,000 miles (by contrast, the moon only gets as close as 225,623 to the Earth). This results in some fairly spectacular views from the surface of the rocky, cratered moon.



Any suggestions of a name for this body would be gratefully received. And my quest for more abnormal life will continue. smile
