6 Most Earthlike Planets That Exist But Humans Didn't Know

Finding exoplanets that might look like Earth is a harder task than finding God.

Is the Milkyway galaxy filled with habitable planets? Is that true? The possibility that there might be life on other planets is something which has fascinated the world for a very long time. We human always love to explore in order to find a better place for our survival. But, what if that location exists in the outer space?

NASA's space observatory Kepler discovered that there could be around 10 billion potentially habitable planets present in our Milky way galaxy. Yes, you heard it right, 10 billion! So probably it would be an easy task for our astronomers to find one good "blue ball" for future homo sapiens. After all, this is what many people think.

The hunt for habitable planets around the smallest and coolest stars in the universe is not a new concept for an astrophysicist. There may be another world where human-like life could exist. But, where they are? This question is what we're trying to answer here.

Kepler's observations have shown that:

Our galaxy is blessed with the abundant amount of small, rocky worlds like our own, and some of them may have the potential of hosting life.

Gliese 667Cc

Gliese 667Cc

It is an exoplanet which lies about 22 light-years away from Earth. Gliese 667Cc is at least 4.5 times bigger than the size of the Earth. It takes nearly 28 days to complete one orbit around its host star. 

It is a small red dwarf star which seems to be much cooler than the sun, so the exoplanet is believed to lie in the habitable zone.

It was discovered with the help of European Southern Observatory's 3.6-meter telescope in Chile.

Kepler-22b

Kepler-22b

Kepler-22b is the first extra-solar planet, which lies 600 years-away. It was the first Kepler planet which is found by the Kepler space telescope in the habitable zone of its parent star. Its orbit is about 290 days long, and it is 2.4 times bigger than our planet's size.

Kepler-69c

Kepler-69c

Kepler-69c is also known as "super-Venus." It is an exoplanet which is about 2,700 light-years away from Earth. Its orbit of 242 days is close to what Venus has in our solar system. It is about 70 percent larger than Earth. So, once again, researchers are unsure about its actual composition.

Kepler-62f

Kepler-62f

Kepler-62f is potentially an Earth-like planet which is about 1,200 light-years away from Earth. It is only 40% bigger than Earth. Its 267-day orbit, however, puts Kepler-62f between the habitable zone.

Kepler-186f

Kepler-186f

It is the first validated Earth-size planet to orbit a distant star in the habitable zone. The size of an exoplanet is at most 10 percent larger than Earth. The extrasolar planet lies about 500 light-years away from Earth.

Kepler-452b

Kepler-452b

Kepler-452b is also known as Earth's close cousin. Its parent star is very similar to our sun, and the planet orbits in the habitable zone. It resides 1,400 light-years away from Earth.

It is about 60 percent wider than the size of our planet.

Earth (for comparison)

Earth (for comparison)

About 70 percent of the Earth's surface is covered with water.

Earth orbits around a star called the sun, which is about 4.5 billion years old and is expected to put out a same amount of energy for several more billion years.
