Dick is asteroid #17458 and also known as 1990 TP7. Dick was discovered by the German astronomers Lutz Dieter Schmadel and Freimut Börngen at the Karl Schwarzschild Observatory, Tautenburg, Germany. Dick seems to be a common Main Belt Asteroid, rather in the Outer Asteroid Belt.

Dick is named after Wolfgang R. Dick, a German astronomer and geodesist. He works for the International Earth Rotation and Reference Systems Service (formerly International Earth Rotation Service) in Frankfurt am Main, Germany. But he is more known for his research in the history of astronomy and book editor.

All astrologers, who write something on Dick, have copied from Mark Andrew Holmes. He states:

Astrologically, asteroid Dick seems to indicate sex or obnoxious behavior or can be a name asteroid for people named Dick.

As a person name asteroid is Dick of course a person name asteroid, that represents people named Dick. But why does Mark Andrew Holmes write the rest of the sentence this way? Although he knows that the asteroid is named after Wolfgang R. Dick and even shows a picture of Wolfgang R. Dick? Is he able to see any obnoxious behaviour or anything sexually explicit on this picture? The asteroid #17269, also known as 2000 LN1 and a member of the asteroid-family Nemesis, is named Dicksmith. What would that mean if associations with English words would always have to be made? Doesn’t Mark Andrew Holmes know that there is more than one language in the world? Would he find it similar logical or funny if the English language would be ignored this way?

Dick is named after a German astronomer. So his name should be assumed to be German too. Dick indeed is a translatable German word! It is in meaning as well as in etymology the same word as the English word thick. So Dick will, besides persons with the name Dick, only represent thickness, thick people, or thick things.
