In order for complex life to survive, there has to be liquid water. Exoplanets extrasolar planet… Get latest news and information related to exoplanets discovered, exoplanet exploration, habitable earth like exoplanets. In September 2012, the discovery of two planets orbiting Gliese 163 was announced. Its proximity means it’s bright enough for astronomers to study the planets’ atmosphere and to determine whether it is conducive to life.
The scientists give it a 97 percent chance of being in the habitable zone making it one of the top most potentially habitable planets discovered.

Note: There is no scientific consensus about terrestrial composition of most of the planets in the list. The side that is always facing the star is so scorchingly hot that it would be impossible to live there as it would melt you alive. It lies somewhat closer to its star than Venus does to the sun and thus revolves faster than Earth. Do the planets beyond our solar system called exoplanets support human life as well? Exoplanets that are orbiting their host star in just the perfect proximity not too close that they are too hot to live in, yet not too far that they are too cold. Also, because of its aging sun, Kepler-452 b might soon experience a runaway greenhouse effect, similar to the one that changed Venus from a potentially habitable world billions of years ago to the sweltering hothouse it is today.
There are an additional 2,368 potential exoplanets from Kepler's first mission yet to be confirmed, as well as 889 from its "Second Light" mission and 1,403 from the Transiting Exoplanet Survey Satellite (TESS) mission. It has a 60% chance of being rocky and gets about two-thirds as much light as Earth. The closest one is Kapteyn b which is only 13 light years away. It completes an orbit every 35.2 days around an orange dwarf star and it receives 40% more heat from its star than our Earth does from the sun. To date, this is the second closest known potentially habitable exoplanet to Earth. With a star that’s 1.5 billion years older than the sun, this exoplanet is considerably warmer than the Earth.
It takes only 23 days and 14 hours for it to complete one orbit around its star. It lies just 11.905 light years from Earth and is the fourth planet of the system in distance to its star, the Tau Ceti. Check out the 10 potentially habitable planets: Discovered in 2012, this unconfirmed exoplanet candidate is one of the most potentially habitable planets being about four times as massive as Earth, making it a “Super Earth”. Found in the constellation of Lyra and just 470 light years away, this planet named Kepler-438 b is only 1.2 times larger than Earth.
This exoplanet may also have Earth-like temperatures, albeit with large seasonal shifts as it orbits its star.
Kaltenegger, L.; Udry, S.; Pepe, F. (2011).
One side of the planet is always facing its star and the other always facing away. It only means that the planet is just 83% similar to Earth. A potentially habitable Earth-sized exoplanet is similar in size and temperature to Earth, according to a new study. It is four times as massive as Earth and if it is a rocky planet, likely over half-again as large. This exoplanet which is believed to be a water world lies just about 1,200 light years away from us in the constellation Lyra making it one of the most potentially habitable planets.  In May 2016, the finding of three Earth-like planets of ultracool dwarf TRAPPIST-1 has been released. The planet is located 300 light-years away from us.
, For yearly lists on physical, orbital and other properties, as well as on discovery circumstances and other aspects, see § Specific exoplanet lists. The star EPIC 201367065 (Yeah, let’s just call it EPIC), is a cool red M-dwarf about half the size and mass of our own sun, and there are three known Super-Earths orbiting around this star. Lying at a distance of 147 light years, this star ranks among the top 10 nearest stars known to have planets. It is also very close to its star, only less than half distance the Mercury is from our Sun. This is a list of exoplanets. “It might be quite challenging at first but over time, we would adapt to the conditions, and perhaps become stockier over a long period of many generations.” Jon Jenkins of NASA’s Ames Research Center in Moffett Field, California said. Here, the best ever list of our most beautiful... 10 Most Potentially Habitable Planets For Humans, Top 10 Stunning And Mysterious Cloud Formations, 10 Alien Races in Contact with Earth Believe it or Not, Top 10 Mysteries of The World We’ll Probably Never Solve, 10 Strange and Mysterious Planets Outside the Solar System, Top 15 Most Beautiful Girls in the world 2020. Questions that we don’t have the answers to. Gliese 832 c has a mass approximately 5.4 times the size of Earth and an orbital period of approximately only 36 days, this is because it lies near the inner edge of its host star’s habitable zone. This is because it orbits a red dwarf. Called Proxima b, the planet is 1.3 times the mass of Earth and has an orbital period of roughly 11.2 Earth days. Kepler – 296 ranks second among the potentially habitable planets. For exoplanets orbiting a single star, the IAU designation is formed by taking the designated or proper name of its parent star, and adding a lower case letter. A provisional IAU-sanctioned standard exists to accommodate the designation of circumbinary planets. Water is essential to life. This does not mean that Kepler-452 b is less habitable than Earth, though.
There is a very real possibility that the outer planet is rocky like Earth. It orbits a red dwarf star called Gliese 832. This exoplanet is tidal locked which means it doesn’t rotate on its axis. Vogt, Steven (2009).
If you lived there, you’d see a yellow sun in the sky, and your year would just last 168 days. This also means that Kepler-452 b receives 10% more energy than Earth. CS1 maint: multiple names: authors list (. Estimates place the probability of finding a habitable planet around Alpha Centauri A or B at roughly 75%. That means that the Earth and this exoplanet are at roughly the same relative spot in their stars’ habitable zone.
Researchers are still looking into whether it might be a rocky planet or not.
It has a radius 1.75 times that of Earth and it completes one orbit every 34.1 days.
A Habitable Planet around HD 85512?
However, with a denser atmosphere that Super-Earths are expected to have, this exoplanet may well render be inhospitable because denser atmosphere could make it much hotter and more like the planet Venus, greatly reducing the chance for life. The three exoplanets orbiting EPIC are 2.1, 1.7 and 1.5 times the size of Earth.  However, Proxima Centauri's classification as a red dwarf casts doubts on the habitability of any exoplanets in its orbit due to low stellar flux, high probability of tidal locking, small circumstellar habitable zones and high stellar variation. As many as 15% of them can have Earth-sized planets in the habitable zones.. Be careful not to step on the wrong side though. If so, this planet could have the right temperature to support liquid water oceans,” said Erik Petigura, a graduate student at the University of California, Berkeley. It completes one orbit every 93 days and is about 1.8 times bigger than Earth. Throughout hundreds of years, the humankind has made remarkable leaps toward progress in science and technology but despite these progresses, there are still things that we know nothing about.
If several planets in the same system are discovered at the same time, the closest one to the star gets the next letter, followed by the other planets in order of orbital size. It is also 1.6 times larger. The convention for designating exoplanets is an extension of the system used for designating multiple-star systems as adopted by the International Astronomical Union (IAU). About 97% of all the confirmed exoplanets have been discovered by indirect techniques of detection, mainly by radial velocity measurements and transit monitoring techniques.
On August 24, 2016, astronomers announced the discovery of a rocky planet in the habitable zone of Proxima Centauri, the closest star to Earth (not counting the Sun). Research about galaxies beyond the local Milky Way galaxy and search for extraterrestrial life on Earth-sized, habitable exoplanets. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun. However, its days may already be numbered. A limited number of exoplanets have IAU-sanctioned proper names. This is called the habitable or “goldilocks” zone. It lies about 1,120 light years away from Earth in the constellation Lyra. On November 4, 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarf stars within the Milky Way galaxy. It completes one orbit every 112 days in its orange dwarf star, Kepler-442. For exoplanets orbiting a single star, the IAU designation is formed by taking the designated or proper name of its parent star, and adding a lower case letter. In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.Note that this does not ensure habitability, and that * represents an unconfirmed planet or planet candidate. Kepler-62 e is a Super-Earth exoplanet that orbits in the inner habitable zone of its star, Kepler-62 (which is slightly smaller and cooler than our sun).
Other naming systems exist.  Letters are given in order of each planet's discovery around the parent star, so that the first planet discovered in a system is designated "b" (the parent star is considered to be "a") and later planets are given subsequent letters. Astronomers are still finding the answers to these questions but through the help of NASA‘s Kepler mission, the answers don’t seem so far away. Another one among the top most potentially habitable planets is Gliese 832 c, located approximately 16 light years away in the constellation of Grus.
You might think, “If Kepler-452 b is the most earth-like planet ever found, why isn’t it on the number one spot?” Well, according to the Habitable Exoplanet Catalogue, at the University of Puerto Rico at Arecibo, so far, the most “Earth-like” exoplanet, based on its size, mass, distance from its star, amount of energy received, etc., is Kepler-438 b. Kepler-452 b has the advantages of the similar star and similar orbital distance, however, its size keeps it out of the top spot.
