yay for more earth like planet artwork!:la: finally found some time to make more art.:) you may or may not have heard about the recent kepler planets and how they are habitable and similar in size to earth. this is one of them, kepler-442b. being slightly larger than earth and slightly colder, it is one of the most earth like planets discovered to date as of january 2015. i enjoyed making this one, but hated doing the atmosphere which took most of the time. other than that, i plan on redoing some of my older planets in this new style you are seing from me, like gliese-667cc and kepler-62e. i think it really gives a sense of realism to the planets and helps you guys better grasp what the planet may look like. and of coarse i will also be putting out new ones too!:D

so please let your eyes enjoy and leave any comments, favs or critiques,  which are always welcome and appreciated!:D

Description

Kepler-442b is a near earth sized planet orbiting the K-type star, Kepler-442 roughly 1,120 light years from earth in the constellation Lyra. It was detected by the kepler space telescope which finds planets by measuring the dip in star light as a planet passes in front of its star as seen from earth and confirmed to exist in January of 2015. The planet orbits within the star's habitable zone which is the distance away from a star where liquid water could exist on a planet or moon's surface given the right conditions. To date is one of only a few earth-sized planets to potentially harbor life and is ranked as one of the most earth like planets to date with an earth similarity index (ESI) of 0.84.

The planet itself is only 1.34 earth radii and so is classified as a terran type world. This means that is is almost certainly a rocky planet with a composition similar to earth's. However, due to the system's great distance from earth, the planet's mass may not be able to be determined with current telescopic technology and so it can only be infered from our models of known exoplanets of similar sizes.

If the planet is indeed earth-like, it is likely to be a cold world with an average equilibrium temperature of 233 kelvin compared to earth's 255 kelvin. If the planet has a dense atmosphere or a lot of green house gases, it could be warmed to more temperate conditions. The planet is also likely to have a higher surface gravity than earth, due to it's larger size.
Because the planet orbits a star smaller than the sun, it is tingeg with an orange glow as most of the light comming from the sun would be closer the reds. This would affect photosynthesis on the planet causing many plants to appear darker in colour and brownish as they tried to absorb most of the light falling on them.

The planet may also have some large moons in orbit, which can increase it's habitability by creating tides in any oceans and warming them. However, because of the planet's proximity to the star, any moons may have their orbits destabilised by the gravity of the star or experience tidal deceleration due to planet possibly rotating slowely and crashing into the planet.

The planet is located near the tidal locking radius of its star and so there is a chance that it may be tidally locked to the star. However, due to the uncertainty in the formation of the planet and its young age, it is unlikely to be tidally locked. If the planet does indeed eperience a day-night cycle similar to earth's, it would increase it's habitability by evenly distributing heat across the planets surface.

At the moment, the planet is the only one known to exist in orbit around the star. However, it is very likely that there are other planets in the system in closer in and further out orbits, as small planets very rarely form alone.

This is, quite simply, excellent. The clouds and oceans all look good, and your astronomical data is spot on. If I know anyone who needs a press release image made, I'll remember to suggest you – this is better than many of the official artists' images I've seen! I do have a couple suggestions though, and they're both science-based...

* Starlight
Kepler-442 is a K class star, which means it's smaller, cooler, and more orange than the Sun. Your image gives a good idea of what Kepler-442b would look like if it were in our solar system, but in it's home system the starlight would probably give its appearance a slight orange tint.

* "Earth-like"
I'm dropping you by one star on originality, purely because your planet is a duplicate of Earth. There's no particular reason why plants on an alien planet would be green. Life on Earth uses several coloured pigments to absorb light, including red, yellow, and purple. Green just happens to be the one which works best in our star's light. In the light of a different star, who knows? Don't be afraid to get creative. Planets which astronomers say are "Earth-like" aren't necessarily like Earth. <img src="e.deviantart.net/emoticons/w/w…" width="15" height="15" alt=";)" data-embed-type="emoticon" data-embed-id="387" title=";) (Wink)"/>

Overall, it's a brilliant image. I'm very impressed.

thank you. sorry for the late reply, i've been very busy the whole week.
as for the earth-like appearance, thats not what i was actually going for. the planet is much bluer in appearance than what you are actually seeing. if i remove the orange glow from the star, you will see the blue hue. i also went for a denser atmosphere too, but that didn't show too well.
all in all thanks for the critique.

Aparrently Kepler-442b is more habitable then Earth. :shrug:
Alpha-Element's avatar
might be assuming it is even rocky.

This is amazing! I like the simple and realistic but impressive look. The surface of the planet is looking great with the clouds.

Can I use this (and your other planets) for my own pictures? It is non-commercial and I'd give the credits to you!
i mean, you wrote, that it is forbidden, but your images are so nice and good to use! 
(Sorry if it sounds unprofessional and kinda childish ^^. I am German )

thanks and sure. but only the exoplanets. so nothing from the new dawn or alpha-element folders.

EPIC, I LOVE IT!!!

Great artwork ! :)

I have a request. Can you make a planet, idc which, with purple life? Great art, btw!
Alpha-Element's avatar
thank you. and i guess i could. it may be a little difficult mixing the colours together but, i could try.
tsahel's avatar
your planet texture is amazing and your clouds gorgeous !
Alpha-Element's avatar
oh thank you! i put a lot of hard work into my planets to make sure they look as realistic as possible.:)
BrainNectar's avatar
Is this a real photograph or a 3D render? It looks so real and quite possible.
Alpha-Element's avatar
its my interpretation of the planet. i created it in photoshop cs5 from flat textures.

Amazing work as usual.

Damn, let's hope they find soon the "tears of unicorn" (exotic matter or whatever) needed to have a working Alcubierre drive and we can visit those worlds.
Alpha-Element's avatar
thanks!:D
i hope they create a fully functioning alcubierre drive that doesn't require the energy of a whole star to travel just a few light years. one that could create a massive distortion in the space time without the use of large amounts of energy.

Very lovely. Very majestic. Glad to see you had time to do something like this. After looking around I had some pretty interesting results for an idea you could do. The binary star system Sirius or Barnards Star, i haven't got into looking if they have planets, but i'm pretty sure you can come up with a hypothetical one (if there isn't any).
Alpha-Element's avatar
glad you like it!:)
i am not very inclined in creating fictional planets around real stars, it just doesn't sit well with me. i'd rather create an entirely fictional one or an entirely real one. but thanks for the suggestions though.;)

HD 209458 b A.K.A, Osiris. Very similar to WASP-12b. Very large gas planet, likely a red color. I dont know man its up to you.
