10 Earth-Like Planets That Could Support Life One Day

Humans have taken giant leaps in the past few decades in matters of science and technology but some intriguing questions never tend to leave us. Questions we don’t have answers to yet. Some of them are: Do we walk alone in this enormous cosmos? Do the planets beyond our solar system have “Goldilocks zone” which can sustain life? Is there any possibility of finding WATER in some of them or what are the chances of discovering an atmosphere where complex lifeforms like us can walk and breath? The most important question is, Do we have a backup plan or particularly some twin of the earth to where we can escape in near future? Here we have narrowed down the expedition of searching such remarkable earth-like planets to just 10!

GLIESE 667 Cc

This is an exoplanet discovered with the European Southern Observatory’s 3.6-meter telescope in Chile. It is only 22 light years away from Earth and is at least 4.5 times as massive as Earth. It revolves around a red dwarf star which is considerably cooler than the Sun so this exoplanet is thought to lie in the habitable zone of its star.

HD 85512 b

It is 3.6 six times bigger than the Earth, has a gravity only 1.4g despite its big size and completes its revolution in just 54 days but unfortunately it is tidally locked which one part of it is always facing its star and the other half is doomed in darkness. In simple words, it doesn’t rotate. This tidal locking reduces the chance of life but there may be a very narrow habitable zone in between the dark and the sunny side where the temperature is adequate!

Kepler-69c

It is 1.7 times the size of the Earth, lies in the habitable zone, has a revolution period of just 242 days and even is a prime candidate to host alien life as predicted by many scientists!

Tau Ceti e

It is 1.8 times larger than Earth and possesses a very stable atmosphere similar to ours and has a stable star too. It is also just 11.9 years away from us which is pretty close when compared to the other planets of the list but with current technology, it is still quite far to reach.

Wolf 1061 c

Its radius is 4 times that of our planet and sits in the habitable zone of its parent star. Its system is just 14 light years away from Earth which means scientists might be able to study the atmosphere of this planet one day.

KEPLER 22b

It was discovered in 2011 and is roughly 2.4 times larger than Earth. It has a year of 290 days as compared to 365 days on Earth and has an average temperature of 22 degrees Celsius. Some researchers have predicted that it may be covered with an ocean due to its large size but that is hard to say for sure as the planet is 600 light years away and will take quite some time to study that in detail.

Kepler 452b

Kepler 452b was discovered in 2015 and is orbiting in a habitable zone of its star similar to our Earth. It is about 1400 light years away and has a revolution period of approximately 385 days. Its surface temperature is estimated between -20 degree Celsius to +10 Celsius.

Kepler 438b

It is an exoplanet and was also discovered in 2015. It orbits around a red dwarf star, significantly smaller and cooler than our Sun. It has a surface temperature between 0 degrees Celsius and 60 degrees Celsius and lies in the habitable zone of its star which is neither too cold nor too hot to sustain liquid water! But then again sadly it is 400 light years away from Earth.

Kepler 186f

It was discovered in 2014 and orbits its star in just 130 days. It is also in the habitable zone where liquid water might exist. Its host star is half the size and mass of Sun but the planet is 500 light years away in Cygnus constellation.

Kapteyn b

Its parent star is a cool red dwarf and it is only 13 light-years away from earth. It is approximately 11.5 billion years old as predicted by scientists that make it only 2.5 times older than Earth. Like all the other planets of the list, it lies in the habitable zone of its star, at a distance which could support liquid water and has a revolution period of only 48 days!
