Unconfirmed Exoplanets
K2-72 e was discovered in 2016 and orbited the K2072 star of the Aquarius constellation. It is an M-Warm Terran, rocky exoplanet only 217 light-years away from the Earth. Proxima Centauri b – It orbits the closest stellar neighbor of the Earth, Proxima Centauri, which is 4.22 light-years away. Proxima Centauri b is 1.27 heavier than the Earth and takes 11.2 Earth days to orbit its star. The scientists announced Proxima Centauri b in 2016.

Wolf 1061 c – This planet takes only 17.9 Earth days to orbit its M-type star, which lies 14 light-years away from the Earth. It has a significant mass, almost 3.41 times the Earth’s. Tau Ceti f – It is a super-Earth exoplanet that orbits a G-type star every 1.7 Earth years. The star is visible from the Earth and sits only 12 light-years away. It has a mass of almost 3.93 times the Earth’s. However, scientists have questioned Tau Ceti f’s and its neighbor’s habitable status. Then, a 2015 study claimed that this label was generous as the exoplanets did not enter habitable zone until under a billion years and cosmically recently.
