The great contribution of Tycho Brahe was to _.
A)discover four moons orbiting Jupiter, thereby lending strong support to the idea that the Earth is not the center of the universe
B)observe planetary positions with sufficient accuracy so that Kepler could later use the data to discover the laws of planetary motion
C)offer the first detailed model of a Sun- centered solar system, thereby beginning the process of overturning the Earth- centered model of the Greeks
D)discover that planets orbit the Sun in elliptical orbits with varying speed

Question

Quizplus · Accepted Answer

Tycho Brahe meticulously observed and recorded the positions of planets, stars, and comets for over 20 years. His accurate observations and measurements provided the necessary data for Johannes Kepler to later derive the laws of planetary motion. Therefore, his great contribution was to observe planetary positions with sufficient accuracy so that Kepler could later use the data to discover the laws of planetary motion.
