1 Jan 1917 Jahr - Adriaan Van Maanen makes the first observation of an exoplanet, then not recognised as such.

Beschreibung:

Adriaan Van Maanen was a Dutch-American astronomer. Strangely enough, he was known for faulty results due to his device, a stereo blink comparator, using 10-20-year-old plates.
