}}{{starbox end}}Alpha Chamaeleontis, Latinized from α Chamaeleontis, is a solitary[19] star in the southern circumpolar constellation of Chamaeleon. It has an apparent visual magnitude of 4.06[3] and thus is bright enough to be seen with the naked eye. With an annual parallax shift of 51.12 mas,[ it is located 63.8 light years from the Sun.]
This is an F-type main sequence star with a stellar classification of {{nowrap|F5 V Fe−0.8}},[4] where 'Fe−0.8' indicates an anomalously low abundance of iron. It has an estimated 1.4 times the mass of the Sun,[11] and radiates 7.64[12] times the solar luminosity from its outer atmosphere at an effective temperature of 6,776 K.[11] The star is around 1.8[11] billion years old with a projected rotational velocity that is too low to be measured.[16] The star has been examined for an infrared excess that would suggest the presence of an orbiting debris disk, but none was found.[28]
