'''HD 131399''' is a [[star system]] in the [[constellation]] of [[Centaurus]]. Based on the system's electromagnetic spectrum, it is located around 350 light-years (107.9 parsecs) away. The total [[apparent magnitude]] is 7.07, but because of [[interstellar dust]] between it and the Earth, it appears {{val|0.22|0.09}} magnitudes [[Interstellar extinction|dimmer]] than it should.

The brightest star, is a young [[A-type main-sequence star]], and further out are three lower-mass stars. A [[Jupiter]]-mass planet or a low-mass [[brown dwarf]] was once thought to be orbiting the central star, but this has been ruled out.{{Cite journal |last1=Wagner |first1=Kevin |last2=Apai |first2=Dániel |last3=Kasper |first3=Markus |last4=Kratter |first4=Kaitlin |last5=McClure |first5=Melissa |last6=Robberto |first6=Massimo |last7=Beuzit |first7=Jean-Luc |date=2022-04-15 |title=Retraction |journal=Science |language=en |volume=376 |issue=6590 |pages=255 |doi=10.1126/science.abq1709|pmid=35420970 |bibcode=2022Sci...376..255W |s2cid=248180563 |issn=0036-8075|url=https://www.science.org/doi/10.1126/science.abq1709 |url-access=subscription }}
