(29470) Higgs is an asteroid located in the central main belt . It was discovered by the Italian amateur astronomer Vincenzo Silvano Casulli on October 26, 1997 at the Osservatorio di Colleverde ( IAU code 596). The observatory founded by Casulli was located from 1981 to 2003 in the city of Guidonia Montecelio in the metropolitan city of Rome .
The period of rotation of the asteroid was studied by Andrea Ferrero from the Bigmuskie Observatory in Mombercelli , Italy in March and April 2016. However, the light curves were not sufficient for a determination due to bad weather.
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel subdivided all examined asteroids into C, S and V types (29470) Higgs assigned to the S asteroids .
(29470) Higgs is a member of the Eunomia family, a group named after (15) Eunomia , which is believed to include five percent of the main belt asteroids. The timeless (non- osculating ) orbital elements of the asteroid are almost identical to those of four smaller ones, assuming the absolute magnitude of 15.4, 15.8, 15.8 and 17.2 versus 13.1, asteroids: (109171 ) 2001 QP 64 , (115169) 2003 SW 80 , (188455) 2004 JC 11 and (502352) 2015 BT 205 .
(29470) Higgs was named on April 6, 2012 after the British physicist Peter Higgs (* 1929).
