110 Herculis (abbreviated to 110 Her) is a star in the northern constellationofHercules. Its apparent magnitude is 4.19,[2] and it can be faintly seen with the naked eye, according to the Bortle scale. Based on parallax estimates made by the Hipparcos spacecraft, the star is located fairly close, about 62.7 light-years (19.21 parsecs) away.[1]
110 Herculis has a spectrum matching that of an F-type main-sequence star. It is about 1.4 to 1.7 times more massive than the Sun, and about two times wider than the Sun. Its effective temperature is about 6400 K. An infrared excess has been detected, indicating the presence of a circumstellar disk.[3]
110 Herculis is the 17th-brightest star in the constellation.[citation needed] It is located in the sky about halfway between RasalagueinOphiuchus and AlbireoinCygnus, offset a trifle west.[citation needed] 110 Herculis, along with its apparent neighbors 111 Herculis, 112 Herculis, and 113 Herculis lie close to the eastern edge of the constellation of Hercules.[citation needed]
