Star in the constellation Hercules
110 Herculis (abbreviated to 110 Her ) is a star in the northern constellation of Hercules . Its apparent magnitude is 4.19, 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.
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 .
110 Herculis is the 17th-brightest star in the constellation. It is located in the sky about halfway between Rasalague in Ophiuchus and Albireo in Cygnus , offset a trifle west. 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.
