(7212) Artaxerxes is an asteroid of the main inner belt that was discovered on September 29, 1973 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made during the 2nd Trojan survey, during which Tom Gehrels surveyed field plates recorded with the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 13 years after the start of the Palomar-Leiden- Surveys .
The Italian astronomer Vincenzo Zappalà defined in a publication from 1995 (et al.) That (7212) Artaxerxes belonged to the Flora family, a large group of asteroids named after (8) Flora . Asteroids of this family move in a 4: 9 orbital resonance with the planet Mars around the sun . The group is also called the Ariadne family, after the asteroid (43) Ariadne . According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (7212) Artaxerxes assumed a light surface, so it could, roughly speaking, be around trade an S asteroid .
(7212) Artaxerxes was named on October 16, 1997 after the Persian great kings Artaxerxes I. Makrocheir and Artaxerxes II. Mnemon .
