HD 198716

HD 198716, also known as HR 7987 or 33 G. Microscopii, is a solitary star located in the southern constellation Microscopium. Eggen (1993) lists it as a member of the Milky Way's old disk population.

The object has an apparent magnitude of 5.33, making it faintly visible to the naked eye under ideal conditions. Based on parallax measurements from the Gaia satellite, it is estimated to be 396 light years away from the Solar System. However, it is drifting closer with a somewhat constrained heliocentric radial velocity of $$. At its current distance, HD 198716's brightness is diminished by 0.1 magnitude due to interstellar dust.

This is an evolved red giant star with a stellar classification of K2 III. It has 2.45 times the mass of the Sun but at an age of 622 million years, it has expanded to 23.9 times the Sun's radius. It radiates 160 times the luminosity of the Sun from its photosphere at an effective temperature of $$, giving it an orange hue. HD 198716 is slightly metal deficient and spins moderately with a projected rotational velocity of $$.
