[10] This star has an orange hue and is bright enough to be faintly visible to the naked eye on a dark night, having an apparent visual magnitude of +4.39.

[2] It is located at a distance of approximately 260 light years from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +71.6 km/s.

[12] The stellar classification of HD 66141 is K2IIIbFe-0.5:,[3] which indicates an evolved K-type giant star with a mild underabundance of iron.

[11] The star is radiating 209 times the luminosity of the Sun from its photosphere at an effective temperature of 4,521 K.[5] A magnitude 10.32 visual companion was reported by J. Glaisher in 1842.

However, in 2024, a study using astrometry from the Gaia spacecraft suggest that HD 66141 b is actually a brown dwarf, with a maximum mass estimated at 23.9+7.2−6.4 MJ, based on a large RUWE in the astrometric solution (which could imply that there is a brown dwarf orbiting HD 66141), but they also note that mechanisms such as calibration errors could also explain the large RUWE.
