It is approximately 86.29 ly from Earth and is a main-sequence star of the spectral type G and luminosity class V. The absolute magnitude of 11 Aquarii is 6.8 meaning its luminosity is less than our own sun and is slightly yellower. The luminosity could be due to a lesser supply of hydrogen for nuclear fusion within the core thus meaning a possibly younger star. The B-V color index of 0.634 of star 11 Aquarii means that it is indeed hotter than our sun but smaller in size because of age and mass.
