Proxima (the name means "nearest") Centauri a dim red dwarf star (not visible to the naked eye) at 4.22 light years away.
It has been the nearest star to us for 35,000 years and will remain so for another 9,800 years
BUT by 11,800 AD Barnard's Star, another dim red dwarf star (not visible to the naked eye) currently at 5.96 light years away, will approach to within 3.8 light years and become the nearest star to us.
AND within 1,400,000 years Gliese 710, another dim red dwarf star (not visible to the naked eye) currently at 63 light years away, will approach to within 1.1 light years and become the nearest star to us, and be as bright as Antares when it does so.

The closest is Proxima Centauri, one of three stars that orbit each other about 4 light-years away in the Alpha-Centauri system. Alpha Centauri is easily visible from Earth's Southern Hemisphere. Next is Barnard's Star, a dim star visible with a telescope in the constellation of Ophiuchus. Sirius, the brightest star in the night sky, is part of the fifth closest star system, from which light takes 8.6 years to reach us. The nearest 25 star systems are shown on the above map, out to 13 light-years. Past that there are probably stars so dim that their proximity has not yet been discovered. Research continues in trying to identify an estimated 130 missing star systems out to 32 light-years.

Alpha Centauri is the nearest star system with 4.37 light years distant.
Proxima Centauri (part of the system) was the NEAREST STAR with 4.22 light years distance.

wiki seems a little unclear about this
yes. Proxima is the closest star within the closest system to us, the Alpha Centauri system

purple, evaluate that The e book of Revelation as in line with it somewhat is unique meaning is an "unveiling" or "non secular epiphany". The term "apocalypse" in basic terms skill "unveiling" and has not something to do with end situations. this concept replaced into delivered approximately later by using literalization of the imagery of John of Patmos' imaginative and prescient. Now visions like desires which come from the subconscious / subconscious recommendations infrequently have a actual or literal magnitude. If we are to be conscious them to the actual international it is going to be understood in terms of subconscious symbolism. Now this may appear somewhat way-out yet in accordance to my very own interpretation and a number of different teachers, it somewhat is is a revelation with regard to the non secular awakening of the Charka's. the actuality that there are 7 scrolls and seven chakras isn't any accident and those attentive to the jap systems can particularly become attentive to the symbolism as being proper to each and each particular chakra (the outlet of the seals on the scrolls). aside variety that the unique Koine Greek version is a ways greater insightful than a unfavorable English translation attempt. besides, in basic terms my interpretation.

proxima centauri. it is a star within the star system alpha centauri, which is commonly mistaken as the closest star. ...it's light years away though, so close is relative.
