The distance to the star can be determined directly through parallax measurements, yielding an estimate of roughly 450 light-years (140 parsecs) with a 6.7% margin of error.

[10] The spectrum of this star matches a stellar classification of B3 IV,[15] with the luminosity class of IV indicating this is likely a subgiant star that has nearly exhausted the supply of hydrogen at its core and is in the process of evolving into a giant star.

In 1969, Chi Carinae was classified as chemically peculiar Ap star[16] because its absorption lines of silicon appeared unusually strong relative to the lines for helium.

However, subsequent examination in the ultraviolet band showed the silicon bands were as expected and it was determined the spectra is normal for a star of its type.

[7] Observation during the Hipparcos mission showed no photometric variability down to a limit of ±0.003 magnitude.
