Tycho Brahe demonstrated that the supernova of 1572 was not a nearby event by proving that it did not show parallax over the course of one night. Parallax is the apparent displacement of an object when viewed from two different positions. If the supernova were close to Earth, it would have shown parallax as Earth rotated on its axis. However, Tycho Brahe observed that the supernova did not move relative to the background stars, which proved that it was not a nearby event.
