Tycho Brahe demonstrated that the supernova of 1572 was far from Earth by observing that it did not show parallax, meaning it did not appear to move against the background of the stars as Earth orbited the Sun. This lack of apparent motion indicated that the supernova was much farther away than the planets and the Moon, which do show parallax.
