this one is overdue by two years. i should have made an artwork for this little planet back when it was discovered. but better late than never i guess.
--> let thou's eyes be appeased by my offering, but do not eat it despite its meat ball-like appearance, because eetz a spizee one! <---- yes... another bad jok.. (hit by a tomato)!
you can find out more about the little rock right here:

Any comments, favs or critiques, are always welcome and appreciated!

Alpha Centauri Bb
Description
Alpha Centauri Bb was discovered by an European Team of Astronomers when they were measuring the radial velocity of the sun-like star Alpha Centauri B in the Alpha Centauri trinary star system. When they removed known sources of interferance from the data, they were left with risudual signals which led to the discovery of the planet. If the planet is confirmed, it would be the closest known exoplanet to be detected , at a distance of just 4.366 ly, and also the smallest mass exoplanet with a minimum mass of only 1.13 earth masses, to be orbiting a sun-like star.
The planet is most likely to have a composition similar to earth's being a third metals and two-thirds silicates. this would give it radius only slightly larger than earths. However, due to its position in the system, it may have formed with a higher concentration of metals and have a density greater than earth's. This would cause the planet to have a radius slightly smaller than earth's. Despite this, the surface gravity is likely to be very similar to earth's.
The planet orbit's extremely closely to the star at only about 4% the earth-sun distance and orbits the star once every 3.2357 days. At such a close distance, it is most likely tidally locked to the star, always presenting the same face toward the star. Also, at such a close proximity to the star, there is likely no atmosphere on the planet due to it being blasted away by the star's powerful stellar wind. These two factors would cause an extreme temperature difference between the day and night sides of the planet.
On the day side, the star would loom as a large disc in the planet's sky and the temperature may be as high as 1,200 Celsius, which is above the melting point of many metals and silicates. This may lead to large pools of lava on the surface of the day side, leading to the depiction of the planet as a lava world. There may be a temporary tenuous atmosphere composed of metal and silicate ions and atoms knocked off of the surface by the star's stellar wind.
On the night side, things would be quite different as the environment plumets to sub-zero temperatures. There would be large formations of rock and metal frozen on the surface in the presence of the biting cold, and probably glazed over with some ices composed of the planets now frozen out atmosphere if any were present on the night side. There may be the occasional hotspot caused by the planet's own internal volcanism, but there would be no warmth anywhere else in the eternal night. Every few years, the primary star of the system, Alpha Centauri A, would be in a position where it would rise and set as a bright star in the night sky of the planet as it orbited Alpha Centauri B, bringing slight illumination to the dark wasteland every few days. But for half of the Binary star's year around each other, the night side would be left in total blackness.

Hmmm...so hitting you up for an ice planet is out of the question?

No problem. I was just one day looking through your lovely gallery and realized hes missing the most important planets!

thanks! did you notice any other of the most important planets that may be missing, because i could fix that problem quickly!

Or Tau Ceti e, or remember that game Halo: Reach? that took place around an actual real life star called Epsilon Eridani, the solar system contains 1 ringed gas giant, and also according to research is very young, as a very large asteroid belt is seen around the star.

Lol even i am running out of ideas. Upsilon Andromedae or Kepler 7b (The first mapped out exo-planet).

Hot jupiters? Hmmm. How bought WASP-12b or TrEs-2b?

Alpha-Element In reply to ToxicFusionHD [2014-10-21 23:39:56 +0000 UTC]
ehh, i was thinking more of osiris or belleraphon, but they may be outside of my current capabilities.

Osiris was interpreted by some to be blue. Belleraphon (Or 51 Pegisi b) is nearly almost the same as WASP 12b. Both are massive gas planets which orbit extremely close to its star, the only noticeable difference is WASP 12b's trail of matter it leaves as it orbits its star, the parent star is literally tearing the apart WASP 12b. In a few thousand years or so the planet wont exist.
