This name was assigned in honor of Prof. Gustav Stracke (1887–1943), famous German astronomer at the Berlin Rechen-Institut, without his knowledge of the meaning. The name is from the Latin word “strenuous” which means strong, careful, and exemplifies virtues of G. Stracke. The German substantive is “Stärke” which sounds quite similar as “Stracke”. (H 111) _ _.
