This artist's concept illustrates a young, red dwarf star surrounded by three planets.

Wolf 1061d or WL 1061d is an exoplanet orbiting the red dwarf star Wolf 1061 in the Ophiuchus constellation, about 13.8 light years from Earth . It is the third and furthest planet in order from its host star in a triple planetary system, and has an orbital period of about 67 days.

Habitability

Although the low stellar flux, the presence of additional greenhouse gases like Methane or even Hydrogen gas might make Wolf 1061d marginally habitable. But due to the high probability of Wolf 1061d being a mini-Neptune combined with questionable prospects of being habitable for Earth-like life in the conventional sense makes this exoplanet a poor candidate for being “potentially habitable”.^[3]
