[5] Based upon an annual parallax shift of 3.75 mas,[1] it is located roughly 870 light years from the Sun.
The primary component is an evolved[6] B-type subgiant star with a stellar classification of B2.5 IV.
[6] It is radiating over 2,000 times the solar luminosity from its outer atmosphere at an effective temperature of 12,904 K.[9] The estimated age of this star is around 24 million years.
[11] At this age, it is thought to be the remnant of a once more massive star that just finished hydrogen fusion, and is undergoing structural readjustment.
This process is extremely short, on the order of ten thousand years, making it a rare object.
