Classified under:
Nouns denoting natural objects (not man-made)
Instance hypernyms:
flare star (a red dwarf star in which luminosity can change several magnitudes in a few minutes)
Holonyms ("Proxima" is a member of...):
Centaur; Centaurus (a conspicuous constellation in the southern hemisphere near the Southern Cross)
Context examples:
Just over 4 light-years away, Proxima is the closest star to Earth, besides our own sun.
(ESO Discovers Earth-Size Planet in Habitable Zone of Nearest Star, NASA)
The specifics of Proxima B's orbit are not yet established.
(Simulations show planet orbiting Proxima Centauri could have liquid water, Wikinews)
Many red dwarf stars, including Proxima Centauri, are subject to flares that occasionally bathe their orbiting planets in deadly ultraviolet and X-ray radiation.
(Closest Temperate World Orbiting Quiet Star Discovered, ESO)
The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri.
(ALMA Discovers Cold Dust Around Nearest Star, ESO)
These results provide the basis for future studies to determine the habitability of Proxima b.
(Planet Orbiting Nearest Star Could be Habitable, NASA)
The new planet circles Proxima Centauri, the smallest member of a triple star system known to science fiction fans everywhere as Alpha Centauri.
(ESO Discovers Earth-Size Planet in Habitable Zone of Nearest Star, NASA)
Proxima B is believed roughly Earth-sized and in its solar system's habitable zone, meaning it would have similar gravity to Earth and at least the possibility of liquid water.
(Simulations show planet orbiting Proxima Centauri could have liquid water, Wikinews)
These new observations reveal the glow coming from cold dust in a region between one to four times as far from Proxima Centauri as the Earth is from the Sun.
(ALMA Discovers Cold Dust Around Nearest Star, ESO)
This planet, called Proxima b, is in an orbit that would allow it to have liquid water on its surface, thus raising the question of its habitability.
(Planet Orbiting Nearest Star Could be Habitable, NASA)
The science team that made the discovery determined that the new planet, dubbed Proxima b, is at least 1.3 times the mass of Earth.
