Wolf 1061c

This exoplanet is located about 13.8 light-years from Earth in the constellation Ophiuchus, making it the second-closest known potentially habitable planet to Earth, after Proxima b.

Wolf 1061c lies within the habitable zone of the red dwarf star called Wolf 1061, according to a 2015 study published in The Astrophysical Journal Letters. The exoplanet takes about 17.9 days to complete one orbit around its parent star. Its estimated mass is about 4.3 times that of Earth. Wolf 1061c is thought to be a rocky planet, which means it may be able to support life as we know it.

Gliese 832c

This alien world is slightly farther from Earth, but it exhibits many similar traits that suggest it may be able to support life, too.

Gliese 832c is located just 16 light-years from Earth and lies within the habitable zone of a red dwarf star called Gliese 832. This exoplanet completes one orbit around its star in 36 days.

Gliese 832c is what astronomers call a “super-Earth,” because it is at least five times as massive as Earth. It was actually the second planet found around the star Gliese 832. However, the other one, Gliese 832b, is a gas giant that is likely unable to support life.

Gliese 667Cc

This exoplanet is also considered a “super-Earth,” because it is at least 3.9 times more massive than Earth. It orbits the red dwarf Gliese 667C, which is part of a three-star system that lies 22 light-years away, in the constellation Scorpius.

Gliese 667Cc also lies within the habitable zone of its parent star and takes about 28 days to complete one orbit. Astronomers announced the discovery of this alien world in 2011. It was found using the European Southern Observatory’s (ESO) 3.6-meter telescope in Chile.

TRAPPIST-1d

This exoplanet orbits around an ultracool dwarf star known as TRAPPIST-1, which lies approximately 40 light-years away from Earth in the constellation of Aquarius. TRAPPIST-1d also resides within the habitable zone around its star.

Astronomers announced the discovery of the TRAPPIST-1 system on May 2, 2016. This alien solar system has three potentially Earth-like planets that orbit the dwarf star.

Scientists found the TRAPPIST-1 star system and planets using the TRAPPIST(TRAnsiting Planets and PlanetesImals Small Telescope) instrument at the La Silla Observatory in Chile, which is operated by the ESO.

Gliese 163c

This exoplanet also appears potentially habitable and is located 49 light-years from Earth, in the Dorado constellation. Gliese 163c is approximately seven times the mass of Earth, earning it the title of a “super-Earth.”

It lies within the habitable zone around a red dwarf star known as Gliese 163 and takes 26 days to complete one orbit. Gliese 163c is one of two alien planets found orbiting the star Gliese 163. Astronomers found this planet using the High Accuracy Radial velocity Planet Searcher (HARPS), which is mounted on the ESO telescope located at the La Silla Observatory.
