(5197) Rottmann is an asteroid of the main 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 Second Trojan Survey of 1973, during which Tom Gehrels scanned field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar Observatory .
The asteroid belongs to the Eos family, a group of asteroids, which typically have large semiaxes 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.
(5197) Rottmann was named after the German landscape painter Carl Rottmann (1797–1850), who is known for mythical - heroic landscape painting and whose main work is the Greece cycle.
