SIMBAD data

HD 92063 is a single [8] star in the southern constellation of Carina. It has the Bayer designation t1 Carinae, while HD 92063 is the star's identifier from the Henry Draper Catalogue . This is a suspected variable star [4] and is visible to the naked eye with an apparent visual magnitude of 5.08. [2] The star is located at a distance of approximately 246  light years from the Sun based on parallax, but is drifting closer with a radial velocity of −10 km/s. [1] Although it appears at the edge of the Carina Nebula, it is much closer than the nebula. It is also not considered a member of the nearby Alessi 5 open cluster of stars. [9]

This is an aging K-type giant star with a stellar classification of K1III, [3] having exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. At present it has 14 [1] times the radius of the Sun. The star is radiating 72 [1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,520 K. [1]
