Alleghenia (
Friedrich Schwassmann at Heidelberg Observatory in southern Germany.[6]
The
rotation period of 21.953±0.001 hours with a brightness amplitude of 0.20 in magnitude. It was the last among the first 500 numbered asteroids to have its period measured for the first time (also see 398 Admete).[5]
The minor planet was named by Max Wolf in honor and gratitude of U.S. optician
5502 Brashear
was later directly named after the famous American astronomer and instrument builder.
