Nu Telescopii (ν Telescopii) is a solitary, white-hued star in the southern constellation of Telescopium. With an apparent visual magnitude of +5.35, it is faintly visible to the naked eye. There is a faint magnitude 9.3 companion star at an angular separation of 102 arc seconds along a position angle of 333°, as of 2010. The estimated distance to Nu Telescopii, based upon an annual parallax shift of 20.18 mas, is about 162 light years.
At the age of around 686 million years, Nu Telescopii shows the spectral characteristics of an evolving A-type star with a stellar classification of A7 III–IV. Here, the luminosity class of III–IV indicates mixed traits of a subgiant and a giant star. It has about 1.85 times the mass of the Sun and 2.1 times the Sun's radius. Based upon its motion through space, it is a candidate for membership in the IC 2391 supercluster.
