109 Herculis, also named Tusizuo, is a single star in the northern constellation of Hercules. It is visible to the naked eye as a faint, orange-hued point of light with an apparent visual magnitude of 3.84. The star is located around 121 light-years (37 parsecs) distant, based on parallax. It is moving closer to the Earth with a heliocentric radial velocity of −58 km/s, and may come as close as 81 light-years away in around 328,000 years. This is an aging giant star with a stellar classification of K2IIIab. It is a red clump giant, meaning it is on the horizontal branch and is generating energy through helium fusion at its core. The star is roughly six billion years old with slightly more mass than the Sun. With the supply of hydrogen at its core exhausted, it has expanded to nearly 12 times the Sun's radius. The star is radiating 52 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,569 K.
