Christa (b. 1938) and Günter Rothermel (b. 1938) are the parents of Jens Rothermel, one of the discoverers of this minor planet. They led him to astronomy as his hobby. They support their two children (Thomas and Jens) in an excellent way. The family lives at the "Bergstrasse", a beautiful region in Germany.
