Mu Telescopii, Latinized from μ Telescopii is a solitary star in the southern constellation Telescopium. It has an apparent visual magnitude of 6.28,[2] placing it near the limit of naked eye visibility. The object is relatively close at a distance of 118 light years[1] but is receding with a heliocentric radial velocity of Template:Val.[5]

Mu Telescopii has a stellar classification of F5 V,[3] indicating that it is an ordinary F-type main sequence star. It has been noted to be chromospherically active.[3] The star is 2.12 billion years[11] old with a current mass of Template:Val,[7] and has a diameter 1.4 times that of the Sun. It is radiating 3.22 times the luminosity of the Sun[9] from its photosphere at an effective temperature of 6,570 K,[10] giving a yellow white hue. Mu Telescopii is slightly metal deficient with an iron abundance 87% that of the Sun[11] and spins with a projected rotational velocity of Template:Val.[12]

It has been observed for infrared excess suggesting the presence of a debris disk but so far, none has been found.[15]
