(Proxima Centauri B)
(exoplanet orbiting Proxima Centauri)
Proxima B (short for Proxima Centauri B) is an Extra-Solar Planet orbiting
Proxima Centauri, a Red Dwarf which is part of the triple-star
system, Alpha Centauri. Proxima B is known for
orbiting in its star's Habitable Zone and for being the nearest
known exoplanet to us.
It was found in August 2016 through studies of the star's Radial Velocity.
It orbits the star in 11 days. Its Orbital Inclination is unknown,
limiting our knowledge of its mass: we know only that it is
in the range of 1.25 to 3 Earth masses.
Its presence in a habitable zone makes it of research interest.
It is unknown whether it is rocky.
Its actual Habitability seems
unlikely because of the star's Stellar Wind.
