It is dimly visible to the naked eye with an apparent visual magnitude of 5.53. Based upon parallax measurements, it is located approximately 403 light-years away from the Sun. The radial velocity is poorly constrained, but it appears to be drifting further away at the rate of about $$

This object has a stellar classification of A0 IV, matching an A-type subgiant star. It has 2.6 times the mass of the Sun and an effective temperature of $$, giving a bluish white glow. Due to its slightly enlarged radius, the star has a luminosity over 90 times that of the Sun and spins rapidly with a projected rotational velocity of $16 km/s$. Mu1 Chamaeleontis' metallicity – elements heavier than helium – is 66% that of the Sun.
