57P/du Toit–Neujmin–Delporte
57P/du Toit–Neujmin–Delporte is the designation of a periodic comet. It is a member of the Jupiter family of comets whose orbits and evolution are strongly influenced by the giant planet. In 2002 it was discovered to have broken up into at least 20 fragments. At the time of their discovery, these shed fragments were spread out along the orbital path subtending an angle of 27 arcminutes from the comet's surviving head.
