ET Virginis is a single, red-hued star in the equatorial constellation of Virgo. It can be viewed with the naked eye, having an apparent visual magnitude of 4.91. Based upon an annual parallax shift of $18.58$, it is located 560 light years away. It is moving further from the Earth with a heliocentric radial velocity of +18.6 km/s, having come within 54.31 pc of the Sun around 6.3 million years ago.

This is an evolved red giant star with a stellar classification of M2 IIIa. It is a semiregular variable star of subtype SRB with a magnitude that ranges from a high of 4.80 down to 5.00. The measured angular diameter of this star, after correcting for limb darkening, is $−0.21$. At its estimated distance, this yields a physical size of 83 times the radius of the Sun.
