Question

Quizplus · Accepted Answer

Tycho Brahe is known for his highly accurate and extensive observations of the planets, which he made using a large quadrant instrument he designed and built himself. His data was used by later astronomers, including Johannes Kepler, to develop the laws of planetary motion. While Tycho Brahe did make some innovations in scientific instruments, such as improving the design of the sextant, he did not invent the astrolabe (which had been in use since ancient times) or work out the theory of inertia (which was developed by Galileo). Tycho Brahe also did not calculate the pull of gravity on the tides by the moon or precisely measure the distance to the sun.
