(9680) Molina is an asteroid of the main inner belt that was discovered on October 22, 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 .
In a publication from 1995 (et al.), The Italian astronomer Vincenzo Zappalà defines (9680) Molina as belonging 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 .
(9680) Molina is named after the Mexican chemist Mario J. Molina who, together with Paul J. Crutzen and Frank Sherwood Rowland , received the Nobel Prize for Chemistry in 1995 for work on the chemistry of the earth's atmosphere , especially on the formation and depletion of ozone . The asteroid was named on November 11, 2000. The asteroid of the inner main belt (9679) Crutzen was named after Paul J. Crutzen on the same day , after Frank Sherwood Rowland also on November 11, 2000 the asteroid of the outer main belt (9681) Sherwoodrowland .
