(8433) Brachyrhynchus is an asteroid of the central main belt that was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .

According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (8433) Brachyrhynchus assumed a bright surface, so it could, roughly speaking, be around trade an S asteroid .

(8433) Brachyrhynchus is named after the short-billed goose , whose scientific name is Anser brachyrhynchus . The short-billed goose population is described in the name description of the asteroid discoverers as endangered in the Netherlands. It was named on February 2, 1999. The population in the Netherlands has been increasing since then.
