619 Triberga is a main belt asteroid.

Triberga has an orbit that repeats itself almost exactly every four years in respect to the position of the Sun and Earth. This fact has helped calculate the mass of the moon.

Since it has an absolute magnitude of 9.9, it is roughly 43km in diameter. It has an opposition apparent magnitude of 13.5.
