EC 20058-5234 (QU Telescopii), is a star in the constellation Telescopium.

With an apparent magnitude of 15.03,[3] it's impossible to detect with the naked eye and requires a powerful telescope to be seen; this degenerate object is located 388 light years from the Solar System based on parallax.

[2] QU Telescopii has a classification of DB2, which states it's a white dwarf with He I lines present in its atmosphere.

At the moment, it has 56.9% the mass of the Sun,[7] but a high surface gravity suggests QU Telescopii has a low radius.

[6] First noticed in the Edinburgh-Cape Blue Object Survey published in 1992, it was found to be variable in 1995.
