[11] It is relatively near to the Sun, with a distance of about 29.5 light years as determined from parallax.

Stellar modelling indicates it is near the end of the subgiant stage and about to transition into a giant.

[8] The star has 2.35 times the size of the Sun and is radiating three times the Sun's luminosity from its photosphere at an effective temperature of 5,022 K.[7] Delta Eridani is catalogued as a suspected RS Canum Venaticorum variable in 1983,[14] but the activity level for the star is very low that this is considered a mistake.

However, an examination of the star using interferometry does not detect the presence of a companion at the expected distance.

[16] Consequently, the Chinese name for δ Eridani itself is 天苑三 (Tiān Yuàn sān, English: the Third Star of Celestial Meadows.
