(10951) Spessart is an asteroid of the main belt , which was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made 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 ( IAU code 675) .
The celestial body belongs to the Eos family, a group of asteroids, which typically have large semi-axes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
The asteroid was named on May 1, 2003 after the Spessart , a low mountain range between Vogelsberg , Rhön and Odenwald in Bavaria and Hesse . It comprises the largest contiguous area of mixed deciduous forests in Germany and is located north of the Main , which forms the border with the Odenwald - about 55 km east-southeast of Frankfurt and 40 km west-northwest of Würzburg . The highest point is at 586 m above sea level. NHN the Geiersberg in the High Spessart .
