Wolf 1061b is anexoplanet orbiting thered dwarf star Wolf 1061 in theOphiuchus constellation, about 13.8light years fromEarth. It is the first planet in order from its host star in atriple planetary system, and has anorbital period of nearly 5 days. The planet orbits too close to itsstar for it to be in the habitable zone.^[3]
