( 9681 ) Sherwoodrowland is an asteroid of the outer main belt, which was discovered on 24 September 1960 by the Dutch astronomer Cornelis Johannes van Houten couple and Ingrid van Houten - Groeneveld. The discovery came as part of the Palomar - Leiden Survey, which recorded by Tom Gehrels with the 120 - inch Oschin Schmidt telescope at Palomar Observatory field plates at Leiden University were screened.

The asteroid is part of the Eos family, a group of asteroids, which typically have semi-major axes from 2.95 to 3.1 AE, bounded on the inside of the Kirkwood gap in the 7:3 resonance with Jupiter, and orbital inclinations between 8 ° and 12 degrees. The group is named after the asteroid (221 ​​) Eos. It is believed that the family was created over one billion years ago by a collision.

The timeless ( nichtoskulierenden ) orbital elements of ( 9681 ) Sherwoodrowland are almost identical with those of nine smaller when one of the absolute brightness of 14.4, 14.4, 14.5, 15.1, 14.6, 14.5, 14.6, 15.7 and 16.0, compared to 13.4 emanates, asteroids: ( 10173 ) Hanzelkazigmund, ( 72853 ) 2001 HE42, ( 91821 ) 2001 TN277, ( 159524 ) 2001 FO96 ( 163541 ) 2002 TC77, ( 192211 ) 2007 KO3, ( 195771 ) 2002 PK131, ( 255 174 ) in 2005 and UL226 ( 313 910 ) in 2004 PO63.

( 9681 ) Sherwoodrowland is named after the American chemist Frank Sherwood Rowland, who won in 1995 with Paul J. Crutzen, Mario J. Molina and for work on the chemistry of the Earth's atmosphere, particularly the formation and decomposition of ozone, the Nobel Prize for Chemistry. The naming of the asteroid on 11 November 2000. According to Paul J. Crutzen of the inner main belt asteroid ( 9679 ) Crutzen was named on the same day, according to Mario J. Molina also on 11 November 2000, the asteroid of the inner main belt ( 9680 ) Molina.
