[2] Based upon an annual parallax shift of 25.30 mas as measured from Earth,[1] it is located around 129 light years from the Sun.
[4] This is an A-type subgiant of spectral type A2IVn,[3] a star that has used up its core hydrogen and has begun to expand off the main sequence.
[5] This is giving the star an oblate shape with an equatorial bulge that is an estimated 18% larger than the polar radius.
[8] The star displays an infrared excess, suggesting the presence of a circumstellar disk of orbiting dust.
[9] Epsilon Gruis is suspected of having a moderately active[10] close companion,[11] which is most likely the source of the weak X-ray emission from these coordinates with a luminosity of 1.3×1028 erg s−1.
