Psi Ophiuchi

Psi Ophiuchi, which is Latinized from ψ Ophiuchi, is a single star in the equatorial constellation of Ophiuchus, located next to the western constellation border with Scorpius. It has an orange hue and is visible to the naked eye as a faint point of light with an apparent visual magnitude of 4.50. The distance to this object is approximately 199 light years based on parallax.
This is an aging giant or bright giant star with a stellar classification of K0- II-III, which indicates it has exhausted the supply of hydrogen at its core then cooled and expanded. At present it has 11 times the girth of the Sun, while having 1.6 times the Sun's mass. It is a red clump giant, meaning it is on the horizontal branch and is generating energy through core helium fusion. The star is radiating 66 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,864 K.
