Quizplus · Accepted Answer

Tycho Brahe failed to detect parallax for the nova of 1572 indicating that it was beyond the orbit of Earth's moon. Parallax is the apparent shift in the position of an object when viewed from two different locations, and is used to determine the distance of celestial objects. If the object is close enough, the shift in position will be detectable, but Tycho's failure to detect it suggests that the nova was too far away to observe any parallax.
