It was discovered by NASAs Kepler Space Telescope in Decembe.
It is located about 600 light-years (180 pc) from Earth in the constellation of Cygnus. You can spawn the solar system instantly, the Earth with Saturn-like rings, or a perfectly-engineered solar system where there are as many planets fit around the habitable zone of a star as. Kepler-22b (also known by its Kepler object of interest designation KOI-087.01) is an exoplanet orbiting within the habitable zone of the Sun-like star Kepler-22. For starters, there are a number of pre-simulated situations. The larger outer planet falls just outside the outer boundary of the habitable zone and is also likely to be rocky, while the smaller inner planet is too close to the star to be habitable. There is a mind-bogglingly large amount of things to do in Universe Sandbox 2. Their masses are at least 1.4, 4.3 and 5.2 times that of Earth, respectively. The University of New South Wales team who discovered the planets put together this demonstration of the system, with the green area marking the habitable zone. An Earth-like planet would be in a torch orbit. These stars have very long lifetime because they burn their hydrogen slowly. Their luminosity is very dim and red in color. Their mass is below 40 of the mass of our sun, Sol. It is only 4.2 light-years away and is now known to have an Earth-sized planet in its habitable zone. M-type stars are the most common stars in the universe, known as red dwarfs. The closest star to the Sun is a small red dwarf star known as Proxima Centauri. The three newly detected planets orbit the small, relatively cool and stable star about every 5, 18 and 67 days. For a classification of stars see The H-R Diagram. "While a few other planets have been found that orbit stars closer to us than Wolf 1061, those planets are not considered to be remotely habitable," Dr Wright says. "It is fascinating to look out at the vastness of space and think a star so very close to us-a near neighbour-could host a habitable planet.
"It is a particularly exciting find because all three planets are of low enough mass to be potentially rocky and have a solid surface, and the middle planet, Wolf 1061c, sits within the 'Goldilocks' zone where it might be possible for liquid water-and maybe even life-to exist," says lead study author UNSW's Dr Duncan Wright. If the star's surface temperature is outside this range, the inner and outer edges of the habitable zone are calculated from the star's radius, R, and luminosity, L, using This corresponds with a Solar System habitable zone from 0.8 to 1.2 AU. The planet, more than four times the mass of the Earth, is one of three that the team detected around a red dwarf star called Wolf 1061. Universe Sandbox averages these two distances to simulate the habitable zone of a star.
