Headline: Observations of the star Aldebaran in Taurus in 1497 confirmed earlier hypotheses
Summary: In 1497, Copernicus observed the star Aldebaran in the constellation Taurus to confirm suspicions by George von Peuerbach and Johannes Regiomontanus about "peculiarities" postulated by Ptolemy about Earth's Moon's motion. This book was not published, however, until just before Copernicus' death in 1543.
