WISE 1049-5319 System
The WISE 1049-5319 System contains 2 Failed Brown Dwarf Stars and 0 Planets.
0 Planets are habitable candidates
The WISE 1049-5319 System, also known as Luhman 16, is located about 6.5 light years from Earth in the constellation Vela. It is one of the closest known brown dwarf binary star systems to the Solar System and the third closest overall after Alpha Centauri (or Rigel Kentauri) and Barnard’s Star.
Luhman 16 is located within the inner rim of the Orion Arm, within the Local Fluff of the Local Bubble, between the Radcliffe wave and Split linear structures (formerly Gould Belt) in the Milky Way Galaxy, making Luhman 16 about 26,000 light years away from the massive Sagittarius black hole at the center of the Milky Way Galaxy.

How far is WISE 1049-5319 from Earth?
WISE 1049-5319 is about 6.5 light years from Earth, which is roughly 1.9 parsecs or about 61 trillion kilometers (38 trillion miles) away. It’s one of the closest known star systems to the Solar System, only the Alpha Centauri system and Barnard’s Star are closer or comparable in distance depending on how you rank them.
Is WISE 1049-5319 the closest star system?
No, Alpha Centauri is the closest stellar system to Earth at about 4.37 light-years away, while Proxima Centauri is actually the closest single star to us (it’s part of Alpha Centauri).
WISE 1049-5319 (also known as Luhman 16) is not the closest system. It sits farther out at about 6.5 light-years.
There’s also Barnard's Star, which is closer than WISE 1049-5319.
So in order of distance from Earth among nearby systems:
-
Alpha Centauri: about 4.37 light-years (closest stellar system)
-
Barnard’s Star: about 5.96 light-years
-
Luhman 16 (WISE 1049-5319): about 6.5 light-years
Note: Luhman 16 is a brown dwarf binary, not a full hydrogen fusing star system like Alpha Centauri. So it’s among the closest “stellar neighbors,” but not the closest true star system.
What type of stars are in Luhman 16?
Luhman 16 is not made of true stars in the usual sense. Instead, it’s a binary brown dwarf system. It contains two objects:
Luhman 16A: a brown dwarf roughly classified around a L-type object
Luhman 16B: a cooler brown dwarf, classified around a T-type object
Brown dwarfs are sometimes called “failed stars” because they form like stars (from collapsing gas clouds), but they never get massive enough to sustain stable hydrogen fusion in their cores.
Luhman 16A (L-type): warmer, more “star like,” with dusty clouds in its atmosphere (like silicate clouds)
Luhman 16B (T-type): cooler, methane rich atmosphere, more like a giant planet in temperature and chemistry
Final Answer: Luhman 16 contains two brown dwarfs, not true hydrogen fusing stars.
Could WISE 1049-5319 have planets?
Luhman 16 (WISE 1049-5319) could potentially have planets, because brown dwarfs can form in a similar way to stars and may retain disks of material long enough for planets to form. In theory, rocky or gas planets could orbit either of the two brown dwarfs individually or both of them in a wider circumbinary orbit.
However, no planets have been confirmed in the system, and there are significant challenges. Brown dwarfs emit very little heat and light, meaning any habitable-zone planets would need to orbit very close in, where conditions could be unstable. The binary nature of the system also adds gravitational complexity that can make long-term stable planetary orbits harder to maintain.
When was Luhman 16 discovered?
Luhman 16 was discovered in 2013.
It was identified by astronomer Kevin Luhman using data from NASA’s WISE (Wide field Infrared Survey Explorer) mission. The discovery was announced in March 2013, and it was notable because the system is one of the closest known stellar neighbors to the Sun, despite having been hidden for so long due to its very low brightness in visible light.
