SIMBAD data

HD 182893, also known as HR 7388 or rarely 60 G. Telescopii, is a solitary, yellowish-orange hued star located in the southern constellation Telescopium. It has an apparent magnitude of 6.13, [2] making it barely visible to the naked eye even under ideal conditions. Based on Gaia DR3 parallax measurements, the object is estimated to be 328 light years away. [1] However, it is approaching the Solar System with a heliocentric radial velocity of −27  km/s . [5] At its current distance, HD 182893's brightness is diminished by 0.19 magnitudes due to interstellar dust. [12] It has an absolute magnitude of +1.23. [6]

HD 182893 has a stellar classification of K0/1 III, [3] indicating that it is an evolved K-type star with the characteristics of a K0 and K1 giant star. It has 2.42 times the mass of the Sun [7] but at the age of 761 million years, [9] it has expanded to 8.08 times the radius of the Sun. It radiates 36.9 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 5,006  K . [7] HD 182893 is particularly metal enriched with an iron abundance 145% that of the Sun's ([Fe/H] = +0.16). [7] Like most giant stars it spins slowly, having a projected rotational velocity of 1.4  km/s . [8]
