HD 143183 is a red supergiant star of spectral type M3Ia in constellation Norma. It is a member of the Norma OB1 association, at a distance of about 2 kiloparsecs. It is one of the most luminous red supergiants with a luminosity about 300,000 times greater than the Sun (L), and is as well one of the largest stars with a radius over a thousand times that of the Sun (R). It has an estimated mass loss rate of 5×10−5 M per year.[3] It is surrounded by a dozen early-type stars and a circumstellar nebula with a radius of 0.12 parsecs (0.39 ly).

It is possible that HD 143183 is a spectroscopic binary with an OB+ companion but this is considered doubtful.[3] HD 143183 lies approximately 1' from the 10th-magnitude O-class bright giant CD-53 6363, the second-brightest star in the cluster.
