The Triquetrum was invented to study precession of the equinoxes with respect to this astronomical body. Venus eclipses it every 414 years, and its occultation by the moon exposes three fainter companions, whose colliding parallel winds are the chief source of its X-rays. An eclipsing binary with an orbital period of 4 days, its large B1 member is a Beta Cephei-type star whose core hydrogen is approaching exhaustion, while its minor B4 member is gaining mass via Roche lobe overflow. Found by following the handle of the Big Dipper through Arcturus, and then down, it is located between Heze and Syrma in its constellation. FTP, name this dwarf system with median magnitude 0.95, the 15th brightest by magnitude, which is
