HD 95086
HD 95086 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.
