53P/Van Biesbroeck is a periodic comet 7km in diameter.[3]

This comet and 42P/Neujmin are fragments of a parent comet that split around March 1845.[4][5][6] The orbit of 53P/Van Biesbroeck has a Jupiter Minimum orbit intersection distance (MOID) of only 0.009 AU (1,300,000 km; 840,000 mi).[3][7] The next perihelion passage is on Christmas Eve 24 December 2028.[2] The comet is expected to brighten to about apparent magnitude 14.
