(9133) d'Arrest is an asteroid of the main belt , which on 25 September 1960 by the Dutch astronomer Cornelis Johannes van Houten , Ingrid van Houten-Groeneveld and Tom Gehrels at Palomar Observatory ( observatory code 675) in California was discovered.
The asteroid belongs to the Eunomia family, a group named after (15) Eunomia , to which probably five percent of the asteroids in the main belt belong.
(9133) d'Arrest was named on April 2, 1999 after the German-Danish astronomer Heinrich Louis d'Arrest (1822-1875), who shared several comets , the asteroid (76) Freia and 342 deep-sky objects and in 1846 discovered the planet Neptune with Johann Gottfried Galle .
