About Wolf 1069 b:

• It is a potentially habitable exoplanet 31 light-years away from Earth. 
• It orbits a red dwarf star, Wolf 1069.
• Wolf 1069 b lies within its star’s habitable zone.
• Wolf 1069 b receives approximately 65% of the solar radiance that Earth receives.

Q1) What is an exoplanet?

An exoplanet or extrasolar planet is any planet detected beyond our solar system. Exoplanets orbit around other stars and are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit.
