(32726) Chromios is an asteroid belonging to the group of Jupiter Trojans . This describes asteroids that orbit the sun on the Lagrange points on the orbit of the planet Jupiter . It is assigned to the Lagrange point L 5 , that is, (32726) Chromios follows Jupiter in its orbit around the sun by 60 °.
The asteroid was discovered on October 16, 1977 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery took place during the 3rd Trojan survey, during which Tom Gehrels surveyed field plates recorded by the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 17 years after the start of the Palomar-Leiden- Surveys .
(32726) Chromios was named after Chromios , a son of Priam . Chromios was killed by Diomedes during the Trojan War . The naming took place on March 18, 2003. In the case of the asteroids, trailing Trojans are named after Trojan heroes.
