(6938) Soniaterk is an asteroid of the Main Belt . It was discovered on September 25, 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 asteroid was named after the Russian-French painter and designer Sonia Delaunay-Terk (1885–1979), who is considered a representative of geometric abstraction .

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.
