These are the seven most potential aliens in the world that may be residing

These planets meet all the conditions to maintain liquid water - a prerequisite for life to emerge.

Recently, NASA made the world startle when it announced the discovery of more than 1,284 new planets outside the Solar System - also known as exoplanets . This has increased the total number of confirmed planets to over 3,000.

And that's not all. With this finding, scientists had the belief that basically, every star in every galaxy would have at least one planet orbiting it. And in fact, there are more than . 100 billion stars in our Milky Way galaxy.

Every star in every galaxy will have at least one planet orbiting it.

With such a terrible amount, even the least dreamy people must admit that we are not alone in this universe.

To identify a life-capable planet, scientists will rely on two criteria: the solidity of the surface of the planet, and the Goldilock (Hay Goldilock zone) - the distance from the planet to the stars. Suitable holder to maintain liquid water.

Below will be the planets that meet those standards, and have the potential to become the aliens' lair.

1. Alpha Centauri star system (2016)

Alpha Centauri is a 3-star system only 4 light years away.

It has been discovered for a long time, but just recently, this star system is believed to have the most potential to nourish a life-sustaining planet.

All thanks to the breakthrough project of Stephen Hawking and billionaire Yuri Miner. They will launch small robots with the iPhone in search of life around Alpha Centauri.

2. Star system Trappist-1 (2016)

This is a brown dwarf about 40 light years away from us.

Also in 2016, NASA found Trappist-1 - a brown dwarf about 40 light-years away, and there were three Earth-like planets orbiting around it.

In fact, only one of these is in the Goldilock region. But the other two planets have one face always facing the host star, so even though they are far away, there is a possibility that they have liquid water and nourish life.

3. Kepler-442b (2015)

This planet is dubbed the "2nd Earth".

In July 2015, NASA announced the discovery of Kepler-442b, the planet was dubbed the "2nd Earth" . The planet is about the same size as the Earth, 1,400 light-years away.

According to scientists, Kepler-442b possesses a perfect distance from its master star. Even, this planet is considered to be more suitable for life "than the genuine Earth" , because it revolved around the star to 6 billion years.

4. Kepler-186f (2014)

This is one of the first Earth-like planets discovered in the Goldilocks region.

Discovered in 2014, Kepler-186f is one of the first Earth-sized planets discovered in the Goldilocks region.

The planet about 500 light years away from us is only about 10% larger than Earth, and there is plenty of evidence that it is a rocky planet.

Kepler-186f master star is redder and cooler than our Sun.

5. Kepler-62 (2013)

The planet is more massive than Earth and is located in the Goldilocks region.

Kepler-62 is a star whose temperature is slightly lower than the Sun, located 1,200 light-years away. And this is the master star of two planets that have the potential to sustain life: Kepler-62e and Kepler-62f.

These are all planets larger than Earth, and are located in the Goldilock area of ​​Kepler-62.

6. Gliese 667 Cc (2011)

This planet has four times the mass of Earth.

In 2011, astronomers discovered Gliese 667 Cc. The planet revolves around a red dwarf, only 24 light-years away, and also in the " habitable " area .

The data show that the planet has four times the mass of the Earth, but we still cannot determine the size of the planet, because dwarfs often have low light.

7. Kepler-22b (2011)

Kepler-22b is considered the most Earth-like planet ever.

At the time of its discovery in 2011, Kepler-22b is considered the most Earth-like planet ever.

It fits neatly in the Goldilocks region, with a star similar to the Sun, about 600 light-years away.

Kepler-22b is twice the size of the Earth, and has an average temperature on the planet's surface that falls around 22 degrees C.
