[4] The stellar classification of Alpha Indi is K0 III-IV,[5] meaning that it has exhausted the hydrogen at its core and evolved away from the main sequence, being now halfway between a subgiant and a giant star.

The effective temperature of its photosphere is 4,900 K,[4] giving it the characteristic orange hue of a K-type star.

[7] In China, this star is called Pe Sze where it also was known as the Persian, a title from the Jesuit missionaries.

[10] The term Pe Sze is from the name of asterism 波斯 (Bō Sī, English: Persia).

In Chinese astronomy, consequently, α Indi itself is known as 波斯二 (Bō Sī èr, English: the Second Star of Persia)[11]
