(12647) Pauluspotter is an asteroid of the main outer belt . It was discovered on September 30, 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 defines in a publication from 1995 (et al.) That 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 , as well as 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.
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), Pauluspotter was assigned to the taxonomic class of C asteroids in a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel (12647) .
The asteroid was named after the Dutch Baroque landscape and animal painter Paulus Potter (1625–1654). It was named on November 14, 2016 at the suggestion of Willem Fröger , a Dutch astronomer who works in Argentina . The Venus crater Potter on the northern hemisphere was named in 1994 after the English children's book author and illustrator Beatrix Potter .
