Question

Which of the following is not contributed to tycho brahe?a)He measured the parallax of a supernova and showed that it was farther away than the Moon

b)He measured the parallax of a comet and showed that it was farther away than the Moon
c)He measured the parallax of stars, showing that the Earth orbits the Sun
d)He measured the positions of the planets with unprecedented accuracy, making it possible for Kepler to determine their orbits

Answer 1

Tycho Brahe did not measure the parallax of stars to show Earth's orbit around the Sun. His accurate pre-telescopic measurements helped lay the foundation for Kepler's laws of planetary motion.

option c. is correct .

Step-by-step explanation:

Among the contributions attributed to Tycho Brahe, the statement that he measured the parallax of stars, showing that the Earth orbits the Sun, is not accurate. Brahe's observation methods were pre-telescopic and his measurements, although precise, did not reveal stellar parallax.

Instead, he made significant contributions by measuring the parallax of a supernova and a comet, both showing that they were farther away than the Moon. Moreover, his meticulous observations of the positions of the planets were crucial for Johannes Kepler to formulate the laws of planetary motion, bolstering the heliocentric model on a solid mathematical foundation.
