(776) Berbericia ( Latin Berbericia ) is an asteroid of the main belt belonging to the dark spectral class C. It was discovered on January 24, 1914 by the German astronomer Adam Massinger at the Heidelberg Observatory and named after the German astronomer Adolf Berberich [2] .

In the late 1990s, an international group of astronomers collected data on light curves of 10 new asteroids, including Berbericia, to use them to create three-dimensional models of these objects [3] .
American astronomers Richard P. Binzel (Eng.) And Shelte Bas published a study in 2003 that further expanded our knowledge of this asteroid. This spectrographic study, conducted from August 1993 to March 1999, is known as SMASSII (Small Main-belt Asteroid Spectroscopic Survey), which made it possible to refine the spectral classes of asteroids [4] .
