Its apparent magnitude is 3.30, meaning that it can be seen with the naked eye (see Bortle scale).

This is a relatively wide visual binary consisting of two G-type red giant stars, both with spectral types of G8III. The two orbit each other every 170.7 years and have a relatively eccentric orbit. The stars are separated by almost one arcsecond. The presence of similar-brightness stars at such separation has made parallax measurements difficult, often with margins of error higher than the standard value, since these measurements assume the star to be single. Based on the typical absolute magnitude of a G-type giant and the apparent magnitude of the stars, the distance has been estimated at 200 light-years. Despite this, a reanalysis of the (uncertain) Hipparcos data, taking in account the binarity of Beta Phoenicis, found a more likely parallax of Template:Val, corresponding to a distance of Template:Val.
