Theta Doradus

Based upon an annual parallax shift of 6.64 mas as seen from Earth, it is located around 490 light years from the Sun.

With an apparent visual magnitude of +4.82,[2] the star is bright enough to be faintly visible to the naked eye.

This is an evolved orange-hued K-type giant star with a stellar classification of K2/3 III CNIb/II,[3] where the suffix indicates it is a chemically peculiar star with a strong CN band.

It is radiating 426.6 times the solar luminosity from its photosphere at an effective temperature of 4,320 K.[6] In Chinese caused by adaptation of the European southern hemisphere constellations into the Chinese system, 夾白 (Jiá Bái), meaning White Patches Attached, refers to an asterism consisting of θ Doradus and α Reticuli.

Consequently, θ Doradus itself is known as 夾白一 (Jiá Bái yī, English: the First Star of White Patches Attached.
