Parallax measurements by the Gaia spacecraft imply a distance of 20.4 pc (67 ly) to Alpha Caeli.

The primary component (α Caeli A) has a spectral classification of F2V,[6] meaning that it is a main sequence star, currently fusing hydrogen into helium at its core.

[14] Its photoshpere, which is emitting 5 times the solar luminosity, has an effective temperature of 7000 K,[14] so it is hotter than the Sun and has a white hue, typical of early F-type stars.

[13] The companion (α Caeli B) is a red dwarf star, with spectral class of M0.5V[6] and absolute magnitude 9.80.

[21] The nearest star to Alpha Caeli is LHS 1678, which is 3.4 light-years from it,[22] closer than Proxima Centauri and Earth at 4.25 ly.
