HD 95086, formally named Aiolos, is a pre-main-sequence star about 282 light-years (86 parsecs) away. Its surface temperature is 7,750±250 K. HD 95086 is somewhat metal-deficient in comparison to the Sun, with a metallicity Fe/H index of −0.25±0.5 (~55%), and is much younger at an age of 13.3 million years. It was originally thought to be part of the Lower Centaurus-Crux association, until it was found using Gaia data that the star may be instead part of the Carina association.
Multiplicity surveys did not detect any stellar companions to HD 95086 as of 2013.
