It is faintly visible to the naked eye with an apparent visual magnitude of 4.71.

[2] The annual parallax shift of the star is 19.7054 mas[1] as measured from Earth, which yields a distance estimate of around 166 light years.

The stellar spectrum displays an overabundance of silicon in the star's atmosphere,[11] but the abundance of iron is the same as in the Sun.

[7] It is around a half billion years old[8] and is spinning rapidly with a projected rotational velocity of 127 km/s.

[3] Epsilon Microscopii is radiating about 36 times the Sun's luminosity[2] from its photosphere at an effective temperature of 9,126 K.[8] Epsilon Microscopii was a latter designation of the star 4 Piscis Austrini.
