The 6 Most Earth-like Planets, According to Scientists

Scientists Always Finding New Home For Humans.

Discovering the first true “alien Earth” is a long-held dream of astronomers — and recent exoplanet discoveries suggest that their dream will come true in the not-too-distant future.

All the planets that I am about to mention have similar atmospheric and environmental conditions as Earth. These planets lie within the “Goldilocks zone,” meaning they are neither too hot nor too cold to support life. And even if there isn’t complete proof of the existence of some of the planets,

6. Gliese 581 d


This exoplanet, which lies just 22 light-years from Earth, is at least 4.5 times as massive as Earth, and researchers aren’t sure whether or not it’s rocky. Gliese 667Cc completes one orbit around its host star in a mere 28 days, but that star is a red dwarf considerably cooler than the sun, so the exoplanet is thought to lie in the habitable zone.

A year lasts 66.87 days, so expect to spend a fortune on calenders. It is also considered a cold planet since it has no proper atmosphere, but to be fair if Earth had no atmosphere we would also have been considered a cold planet with an average temperature of -18°C. In 2009 we beamed 25,880 messages from 190 different countries were sent towards its sun, probably messages begging them not to invade us.

5. Kepler-69c


Kepler-69c, which is about 2,700 light-years away, is about 70 percent larger than Earth. So, once again, researchers are unsure about its composition.

A year is 242 days long, which so far is the closest we got to one year on Earth. Sadly, today it seems to have common properties to Venus which usually means, no chance of life naturally occurring there, ever. It still doesn’t rule it out as a possible place to settle.

4. Kepler-62f


This planet is about 40 percent larger than Earth and orbits a star much cooler than our sun. Its 267-day orbit, however, puts Kepler-62f squarely within the habitable zone.

This planet is 1.4 times the size of Earth, its sun is slightly smaller and cooler than ours, and it would appear to be of peach color to the naked eye if you were to stand on the surface. It would have a rocky surface but with a high probability of water there as well. It is on the target list of SETI for possible life. Sadly it’s 1200 light-years away from us, so the peach sun will have to wait.

3. Kepler-62e


Kepler-62e is a super-Earth exoplanet discovered orbiting within the habitable zone of Kepler-62, the second outermost of five such planets discovered by NASA’s Kepler spacecraft.

Kepler-62e is an exoplanet believed to be a water world, orbiting at about the equivalent distance of Mercury in its planetary system some 1,200 light-years from Earth. The planet is an exciting find to exoplanet researchers because it is close in size to Earth, and also orbits in the habitable region of its star (which is smaller and dimmer than that of Earth’s).

The planet is about 1.6 times the size of Earth and orbits its parent red dwarf star about once every 122 days. It is actually one of two possibly habitable planets in its system. Also present, but farther out from the star, is Kepler-62f, which is about 1.4 times the size of Earth.

2. Gliese 581 g


Gliese 581g is an extra-solar planet candidate within a planetary system that is only 20 light-years from Earth, but at this point, it is highly doubted to exist. First announced in 2010 as a planet close to Earth’s mass in the habitable zone of its host star, the exoplanet has come under scrutiny as other research teams cast doubts on its discovery.

Gliese 581d is the third planet from its host star in the Gliese 581 system, or the fifth planet if you include two unconfirmed planets.

Gliese 581g is an unconfirmed exoplanet in the Gliese 581 system. There are four confirmed and one other unconfirmed planet in the system. The planet is the fourth in order from its red dwarf host star. The mass indicates that it is probable Gliese 581g is a rocky planet with sufficient gravity to hold onto its atmosphere. Gliese 581g is one of the most Earth-like planets detected in the habitable zone of its star.

1. Kepler-452b


This world, whose discovery was announced last month, is the most Earth-like planet found so far, NASA officials say. Its parent star is very similar to our sun, and the planet orbits in the habitable zone. At 1.6 times the size of Earth, Kepler-452b has a “better than even chance” of being rocky, its discoverers have said. Kepler-452b resides 1,400 light-years from Earth.

Kepler-452b may be Earth’s close cousin, but living in the newfound world would still be an alien experience.

A group of pioneers magically transported to the surface of Kepler-452b which is the closest thing to an “Earth twin” yet discovered, researchers announced yesterday (July 23) would instantly realize they weren’t on their home planet anymore.
