619 Triberga is a main belt asteroid discovered on 22 October 1906 by August Kopff at Heidelberg-Königstuhl State Observatory.[1] Since it has an orbit that repeats itself almost exactly every four years with respect to the position of the Sun and Earth, it has been suggested as a way to calculate the mass of the Moon.[8] Triberga was named for the German town of Triberg.[9]
Since it has an absolute magnitude of 9.9, it is roughly 43 km in diameter. It has an opposition apparent magnitude of 13.5.
