The planet — one of the handful to have been discovered to date — is comparable to Earth in terms of both size and orbit.
Scientists discover an 'exceptional' planetary system that might be key to understanding how other systems form
The six-planet system, that was observed by the SOPHIE spectrograph, includes a "super-Earth" and five "mini-Neptunes".
The potentially-habitable planets are fairly close to their suns, making them prime targets for next-gen telescopes.
For a planet to be habitable, it needs to be in the habitable zone where water can exist in liquid form.
There is hydrogen as well as Helium, Nitrogen and Methane may exist, but it can't be detected with any instrument.

The exoplanet Barnard b was confirmed as existing just recently after 20 years of observations.
Super Earths could be forming around young stars in much greater numbers than scientists have thought.
The newly-discovered exoplanet is orbits the fastest moving star in our night sky: Researchers.
All of them are categorised as super-Earths, that is, with masses that are larger than Earth's but less than Neptune's, the study said
While studying K2-18b the researchers also located another planet which was in the same solar system called as K2-18c.
A rocky exoplanet orbiting in the habitable zone of a red dwarf star may be the best place found so far to look for signs of life beyond the Solar System.
A team of Brazilian astronomers has discovered two new planets around a star similar to the sun known as HIP 68468.
NASA's planet-hunting Kepler spacecraft which is carrying out a new mission has made its first exoplanet discovery - a 'super-Earth'.
Astronomers have found a pair of Earth-sized planets orbiting a star similar to the sun, though neither are believed to be suitable for life.
