I must have been very busy or something but I completely missed the announcements in the last couple of years about 2 newly discovered very nearby stars.
Luhman 16 is a binary system of brown dwarfs only 6.6 light years away. These are the nearest brown dwarfs to us. It is the third closest system, only Alpha Centauri and Barnard’s star being closer. Its discovery was announced in 2013.
WISE 0855−0714 was discovered 2014. At 7.5 light years, it is the fourth closest system. It appears to be a singleton.
Both were discovered thanks to the Wide-field Infrared Survey Explorer (WISE).
ROFL. That’s a direct reference to what I posted on the Facebook Dr Karl’s SSSF website ten hours ago. Thank’s DV for adding it here. What I posted there was:
Almost missed this one, never saw it in the news. If you were to list the nearest star systems to us you might list them as: solar system, alpha centauri and proxima, barnard’s star, wolf 359, lalande 21185, sirius. Epsilon eridani with the nearest confirmed planet is significantly further away.
That list is missing some spectacular recent discoveries. Luhman 16 was discovered in the year 2013 and the discovery of Wise 0855-0714 was announced on 21 Apr 2014. Amazingly, both are closer to us than wolf 359 and both were discovered by Kevin Luhman.
Luhman 16 is a binary containing two brown dwarfs and has one suspected planet. Wise 0855-0714 is much fainter, with a surface temperature somewhere between 400 and 600 K, which makes it faint enough to be a jupiter-like planet. If spacecraft ever leave the solar system, Luhman 16 and Wise 0855-0714 would both be well worth visiting.
