!!!!! PLEASE READ DESCRIPTION!!!!!

update 2: made the resolution much higher! 10,000px X 6,000px, my biggest image yet! the planet itself is 5,000px across! file type as png for even more quality! added some background stars using the celestia. their positions relative to the system are fairly accurate.

update: added a contrast layer to the image and now it looks so much better! also added a second moon. gave the planet a little tilt! fixed a few defects in the planets ocean layer. removed some stars and made the stars smaller! added some text.

here, i've made the exoplanet kepler-22b in my depiction of it!

now for its stats:

constellation: Cygnus
star name: Kepler-22
star type: G type, main sequence
system name: Kepler-22
distance from earth: 620 ly

planet name: Kepler-22b
class: super-earth
sub class: ocean world
size: 2.5 earths
gravity: 2.0-2.5 earth gravity
atm. comp.: nitrogen, oxygen, water vapour, other gases, (probably high in carbon dioxide, hydrogen)
atm type: dense, very cloudy
temp: hot
satellites: 2 hypothical/ possibly 2-4
orbit: eccentric
orbital distance: 0.85 au
year: 290 earth days
place in system: inner edge of habitable zone


-they say it is a super earth, ocean world, 2.5 times the size of earth with 2.5 earth gravity.

-it is located in the kepler-22 system, and orbits just on the inside of the stars habital zone, with an eccentric orbit.
so its a moderately hot world, and i've given it an average temperature of 80°C.
now the water won't really boil because of the planets high gravity and dense atmosphere pushing down on the water, but there will be very violent storms and dense clouds, as well as heavy thunder showers. and the heat will generate furoscious winds which i estimate at around 400kmh.

-i estimate chances of life on this world to be around 5-10%.

-because of the planets large gravity, it should have at least 1 or 2 large moons, with a few smaller ones. so i've given the planet two hypothetical moons. the one in the distance is about a little more than 1.5 times the size of our moon. the one in the foreground is about 1/2 the size of of our moon. the moons should also have water, but it may most likely be in the form of clouds in their atmospheres, with a very small chance of there being liquid water on their surface.

this is the very first exoplanet i've ever made, and i assure you that there will be more to come! so enjoy the image!

I love it! I can imagine some of our distant descendants being crazy enough to try to colonize it and tame this world...

glad you like it! and yeah, i guess in the future we'll have the technology that allows us to colonise worlds like this.

Sorry, that should say: smaller average density due to same pressure (proportional analog) and inevitable definition-killing effervescent gas envelope.

Can't resist just a little bit of science pedantry. 2.5 times the earth's size doesn't translate to 2.5 the gravity, anyway the real figure is 2.4 earth radius's. you have to take into account the 1-D dimensional (diameter or radius) increase of the 3-D volumetric increase. Mathematical law states that for three dimensional solids of consistent proportions, twice one dimension is four times the face area and eight times the volume. Given that the gravity at a point -itself a certain distance from the center of gravity of the object (e.g. surface gravity or photosphere)- decreases to one quarter with twice that particular distance, then assuming same density we have a planet with 13.8 times the mass and volume, and therefore 5.76g. Bit much.

not to worry though...
Assuming a greater average density due to distance-proportional mass and increasing pressure area (2.4/2.4^2 = 1/2.4^2) = 0.416) which it probably won't be), then a proportional Earth analog at 2.4 times Earth radius and 13.8 times the volume has 5.74 times the mass and therefore a gravity of about... 2.38g.

Ha! Hows that for a justification?

This is amazing! Did you use any stock, or did you create your own textures?

thanks!
the cloud and moon textures are stock images.

I really dig the planet man! It looks better than the one NASA gave us!

I just downloaded the image and started tweaking it a little... I think you could add "just a little" more contrast with the image. The planet looks sorta "Dull"! But not in a bad sort of way! I just think Kepler could use a little more "Presence" in the piece!

Using the Black/White adjustment works very well for this sort of thing. Just make sure to set the adjustment to "Overlay,Soft,Hard ect..." and depending on the effect you want just adjust the opacity! The planet looks great though! But, remember for space artists "in particular" contrast is a pretty important part of a scene! It helps give dynamic to the art!

P.S I hope you continue this series I think it's pretty awesome!

by kepler's "prescence", do you actually mean the spacecraft in the piece itself, or something else?

and thanks for the constructive feedback and advice, much appreciated! also i'm glad you like the image, and i assure you that the series will continue!
