Pluton, your planets seem a little broken.

Andromeda, they look like that in the official addon as well

Andromeda, they look like that in the whole SE. There are many landscape elements that must be set to 0 so they don't cause trouble. Spiky montes for example are not useable at all but they also have a bug so they crush the planet if set to 0, only can be used 0.01. And there are much more of that. So tired to fight with game mechanics.

Greetings!

Regarding gaseous planets: approximately Earth-mass and Earth-radius gaseous planets have been found. http://www.universetoday.com/107812/kep ... gas-giant/ Most scientists call them "mini-Neptunes"; I prefer the term "gas dwarf", as they probably have relatively much larger rocky/metallic cores than Neptune or Uranus.

Cheers!

Also, speaking of TRAPPIST-1:

Last night I made an addon with my imagination of the TR-1 system. I used data from www.trappist.one which had estimated masses and densities for most of the system. Most of these planets' masses are poorly constrained at present, so for now it's really anyone's guess!

I will gladly explain my reasoning for the presentation of each planet here, if there is interest. In general, I considered that a magnetic field is necessary to the retention of substantial atmosphere; furthermore, that a planet needs a) a (semi-)molten core and b) a relatively fast rotation to maintain a significant magnetic field. While I have considered the TR-1 planets are hypothesized to be tidally-locked, I also noted that some studies suggest a planet can avoid tidal locking in the presence of a substantial hydrosphere and relatively flat ocean floor (thus decoupling the planet's solid surface from its liquid surface, such that only the ocean itself is tidally locked).

Cheers!

I changed your addon a bit, now it's more organized and all the unknown variables are randomized. I also added discovery dates and methods. Unfortunately SE doesn't support luminosity in different wavelengths so TRAPPIST-1 is a bit brighter than it's supposed to be to be able to heat up the planets enough (all infrared radiation shifted to visible).

Just drop the PAK into SpaceEngine/addons.

Also, I have a question: how do we know the temperatures of the planets if they were discovered by their transit?

Andromeda, I think we know it from star characteristics: luminosity 0,000525. But there is something wrong in SE so it doesn't make planets warm enough with that digit. Scientists know things better, need to trust them.

Never mind, I found the answer:

"The main advantage of the transit method is that the size of the planet can be determined from the lightcurve. When combined with the radial-velocity method (which determines the planet's mass) one can determine the density of the planet, and hence learn something about the planet's physical structure. The planets that have been studied by both methods are by far the best-characterized of all known exoplanets."

Mine or Pluton's?
Also as Pluton noted, SE isn't providing the correct luminosity for an M8 V star, but that's easily rectified. SE does do a good job of calculating effective temperatures, but I'm not convinced of its greenhouse calculations, nor of its atmospheres in general. My mod includes (one educated guess at) realistic atmospheres, but obviously all that is pure conjecture given how little we know about these planets so far.
It's also important to note that the error bars on these planets' masses (thus densities) is often greater than half the cited estimates. I personally would love to see the community tackle e.g. higher-end guesstimates, which could make some of TRAPPIST-1's planets into super-Earths or mini-Neptunes.
Cheers!

Doesn't really matter since I deleted everything except for what's been confirmed, but if you want to know it was Pluton's.

Wait, you what? You took my work without asking me and deleted nearly everything from it???

You raise a big fuss about how copyright protection has no place on the internet, and now you take issue with someone releasing a modified version of your work?  You are ridiculous. :)

This is not about copyright or respect. He DELETED stuff. He made his own useless version instead of a designed one.
Look up - there was already 1 upload with ADDING stuff and I am not against it.
