1580, Jun 61599-16521667, Oct 24
a Flemish astronomer. The crater Vendelinus on the Moon is named after him. Around 1630 he measured the distance between the Earth and the Sun using the method of Aristarchus of Samos. The value he calculated was 60% of the true value. Wendelinus was credited with recognizing that Kepler's third law applied to the satellites of Jupiter.
