[2] It is located 472 light-years (145 parsecs) from the Sun, based on its parallax,[1] but is drifting closer with a radial velocity of −45 km/s.
[5] This is an aging K-type giant/bright giant with a stellar classification of K2II/III.
[3] With the supply of hydrogen at its core exhausted, the star expanded and cooled.
It now has 30[1] times the radius of the Sun and is radiating 287[1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,322 K.[1] The star was first designated Lambda Chamaeleontis by French astronomer Lacaille, in his Coelum Australe Stelliferum.
He listed it close to Pi Chamaeleontis in both brightness and location.
