Delta Octantis has the distinction of being Saturn's southern pole star. It has 1.2 times the mass of the Sun and about 25 times the Sun's radius. This star is about 4.3 billion years old; which is similar to that of the Sun.
In Chinese caused by adaptation of the European southern hemisphere constellations into the Chinese system, 異雀 (Yì Què), meaning Exotic Bird, refers to an asterism consisting of δ Octantis, ζ Apodis, ι Apodis, β Apodis, γ Apodis, δ1 Apodis, η Apodis, α Apodis and ε Apodis. Consequently, δ Octantis itself is known as 異雀五 (Yì Què wǔ, English: the Fifth Star of Exotic Bird.)
