There Are More Planets Like Earth in Habitable Zones

The GJs

GJ 667C c- This rocky world is amongst the six exoplanets revolving around GJ 667C and also the only one that lies in the habitable zone. It completes the orbit in 28.1 Earth days and is 3.8 times heavier than the Earth. It is 22 light-years away from us and debuted in 2011. GJ 667C e – This planet takes 62 Earth days to circle its star, as well as it is 2.7 Earth’s mass. It is one of the three worlds that orbit the star GJ 667C. Because this star is located 22 light-years away from the Earth, it is not visible from the Earth. GJ 667C f – This planet also has 2.7 times the Earth’s mass but completes its orbit around GJ 667C in 39 Earth days. 

GJ 1061 c – It is amongst the three exoplanets that orbit the red dwarf star Gliese 1061. This star lies almost 12-light years away from our planet and is the twentieth nearest star to the Earth. GJ 1061 c takes 6.7 Earth days to complete one orbit. GJ 1061 d – GJ 1061 d orbits the star Gliese 1061, which can be detected in the Horologium constellation. It takes 12.4 Earth days for this planet to circle its star. GJ 3323 b – It takes 5.4 days for this super-Earth to complete one orbit around its M-type star. GJ 3323 b a mass 2.02 times the Earth’s and is nearly 12 light-years from the Earth.

The Kelpers

Kepler – 186 f – It was the first exoplanet of the size of the Earth found in a habitable zone and had an orbit of one hundred and thirty Earth days and is nearly 10% larger than the Earth. It seems like Kepler – 186 f would be a good candidate to have liquid water, and probably life. However, it is 490 light-years away from the Earth, in the Cygnus constellation. 

Kepler-62 f – This planet circles around Kepler-62, nearly 1,200 light-years away from the Earth. As per recent research, astronomers believe that this exoplanet may be water-world, similar to the Earth. It is almost 1.4 times bigger than the Earth. Kepler-1229 b – It orbits a K-type star. However, this super-Earth takes almost 86.8 days to complete an orbit around an orange dwarf, Kepler- 1229 that is 770 light-years away from the Earth.

The universe is so vast, who knows what we’ll find next? Shutterstock.

What Else is Out There?

Life on other planets than the Earth has fascinated humans for thousands of years. There are endless questions regarding the same, which need years of research and practice. But one thing is imperative to support life on any planet – water. Other factors that determine whether a world can support growth are its size, orbiting period, distance from its star, and the star type it is revolving around.   

The recent discovery of TOI 770 d and the usage of advanced technologies may help us know more about the unknown worlds out there. Whatever we are going to discover is definitely going to be intriguing and unexpected.
