ι Telescopii, Latinized as Iota Telescopii and abbreviated Iota Tel, is a solitary star[12] located in the southern constellation Telescopium. It is faintly visible to the naked eye as an orange-hued star with an apparent visual magnitude of +4.88.[2] The star is located roughly 377 light years distant from the Solar System based on Gaia DR3 parallax measurements[1] and it is receding with a radial velocity of Script error: No such module "val"..[5] At its current distance, Iota Tel's brightness is diminished by 0.19 magnitudes[13] due to interstellar dust and it has an absolute magnitude of −0.39.[6]
This object is an aging red giant star with a stellar classification of K0 III.[3] At present it has 2.53 times the mass of the Sun,[7] but it has expanded to 19.7 times the radius of the Sun.[8] It is radiating 172 times the Sun's luminosity[1] from its swollen photosphere at an effective temperature of Script error: No such module "val"..[7] Iota Tel has a near solar metallicity at [Fe/H] = +0.01[7] and it spins slowly with a projected rotational velocity of Script error: No such module "val"..[10]
