Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Gamma Virginis is a star in the constellation Virgo. It has the traditional names Porrima, Postvarta and Arich. Gamma Virginis is a binary star, consisting of two stars of approximately equal apparent magnitudes 3.48 and 3.50, and of spectral type F0V. With an orbital period of 168.93 years it was an easy object for amateur astronomers until the beginning of the 1990s, but now the smaller apparent distance between the stars requires a larger telescope. The last time they were at periapsis was in 1836. The distance will again be wide enough in 2020 to view with a small telescope. The star system has a combined apparent magnitude of 2.9. The system is 39 light years away from the Sun.
