Earth like planets have been discovered

The earth was formed before 4.5 billion years ago. Every planet and star which born must die after definite time. Our astronomers are continuous working on finding the solution what after the end of the earth. Some of planets are like to the earth to survive which are in habitable zone of its host star just like the earth. They may be the option for mankind to live.

Some of the planets which are habitable to live as the earth.


The Mars is the forth planet from the Sun and second smallest planet in our Solar System. It is the brightest object in the universe which can be seen by naked eyes. The Mars is recognized as Red planet. Mars have highest chance of life than other planet but still conditions are not enough to survive there. By continues analysis, it is strongly believed that the Mars was once very similar to the Earth. As per recent studies, there may be possibility of water even now on the Mars. One day on the mars is 24.6 hours and one year of 669.6 days. Axis of rotation of mars is tilted about 25.2 degree. The seasons on the mars are too longer than on the Earth since it takes longer to orbit the sun. The seasons on mars vary in length due to elliptical, egg-shaped orbital path around the sun. Average temperature on the Mars’s is about -60 degree Celsius but in winter near poles temperature goes down to -125 degree Celsius. Very heavy dust storms are created on Mars’s surface which has speed about 160km/h which is largest in the solar system.


KEPLER 22B is famous as KOI-087.01 also.  This planet was discovered on 5 December 2011.This exoplanet orbits sun like star Kepler 22B in habitable zone which is 587 light years away from earth in constellation Cygnus. It takes 290 days to complete one revolution around its host star. Its surface temperature about -11 degree Celsius. It is twice in the size of the earth but its mass and surface composition is unknown. This planet is known as ‘water world’ as it is ocean covered planet and rich in water. This planet receives 15% less light from its star as compared to earth. Its orbital path is extreme elliptical so there may be very high temperature variation.


GLIESE 581G is famous as Zermina also. This exoplanet was discovered on September 29, 2010. It orbits the its host star GLIESE 581 in habitable zone about 20 light years away. This planet is tidally locked having average temperature on the planet is -37 to -11 degree Celsius. It is in habitable zone so water is possible on its surface so there may be possibilities of life but atmosphere might be favorable for life. Its one year is equal to 67 days of the earth.


KEPLER 62E was discovered on 18 April 2013. This exoplanet orbits in habitable zone of red dwarf star KEPLER 62 which is about 1200 light years away in Lyra constellation. It is ocean covered planet. It takes 122 days to complete one revolution to its host star. It is 60% bigger than earth. This gaseous planet has surface temperature   -3 degree Celsius.  KEPLER 62E takes 122.3 days to complete one revolution around the star. This star receives 20% more sun light than earth. Water is present on this planet so it may be habitable for terrestrial life form.


GLIESE 667 Cc is also famous as GJ 667Cc or HR 6426Cc or HD 156384 Cc. This exoplanet was discovered on Nov 2011. GJ 667Cc orbits in habitable zone of red dwarf star Gliese 667C about 23.62 light years away in Scorpius constellation. The super earth planet is larger in mass and size than earth having surface temperature is about 4.3 degree Celsius. Its star system is trinary star system. It takes 28.155 days to complete one revolution of its host star. It receives about 90% of lights than earth. This planet is tidally locked so one face is always facing its star and other side is dark, but on the border line of two side is convenient for existing water so it may be habitable for life.


KEPLER 62 F is exoplanet orbiting star Kepler 62 in habitable zone. It was discovered on 18 April 2013. It takes 267.3 days to complete one revolution of its planet. It is rocky planet having surface temperature -65 degree Celsius which is similar to Mars. It receives about 41% of sunlight from its star. Kepler 62F is ocean-covered planet posses rocky surface and water, may be possibilities of having life. This earth like planet is icy and contains atmosphere like earth having carbon dioxide


KEPLER 186F was discovered on 17 April 2014. This exoplanet is similar to earth which orbits to red dwarf Kepler 186 in habitable zone at about 582 light years. It is 11% larger than the earth. Its surface temperature is said -85 degree Celsius. Kepler 186 receives about 5 % of heat from its host star. It takes 129.9 days to complete one revolution of star. Kepler b,c,d and e are also orbit the star Kepler 186. The inner two stars are tidally locked. It rotates very slowly than earth so days are too longer than the earth.


Exoplanet proxima B was discovered on 24 August 2016. It orbits to red dwarf Proxima centauri in habitable zone. It is approximately 4.2 light years far from earth in constellation Centaurus. Proxima B takes 11.2 days to rotate its star. Huge stellar winds are present on this planet which are 2000 times stronger than on the earth from sun. It orbits in habitable zone and as distance from its star where liquid water is exist on its surface. This super earth sized Proxima B has icy composition like Neptune having thick layer of Hydrogen. Its surface temperature is -39 degree Celsius. This planet is tidally locked so any area where water would be exist is border line of two sides and may be possibility for life.


KEPLER 452B is famous as Earth’s cousin. It was discovered on 23 July, 2015.It orbits the Kepler 452 in constellation Cygnus. Kepler 452B is 1400 light years far from Earth which is 20% more luminous than sun. KEPLER 452B is receive 10% more energy from is star than received by earth from sun. It is five times bigger and its gravity is two times than earth. It is super earth having volcanoes on its surface. Its surface is covered by thick misty clouds. Its surface temperature is higher than the earth. It takes 385 days to rotate around its star in habitable zone. Water is found on its surface so possibility of life on it.


KEPLER 438B is the rocky earth’s sized exoplanet. It was discovered on 11 January, 2015. It orbits to red dwarf Kepler 438 which produces 10 times more heat than the sun and about 640 light years far from the Earth. It has temperature about 276K ( 3 degree Celsius) which is close to the earth. Kepler 438B completes one revolution around its star in 35.2 days. It is tidally locked means its one face is always towards its star. It is 12% bigger than the earth. Water also found on its surface.

Have a nice day !!!
