What was one of the contributions that Copernicus made to astronomy?

Nicolaus Copernicus was a Polish astronomer known as the father of modern astronomy. He was the first modern European scientist to propose that Earth and other planets revolve around the sun, or the Heliocentric Theory of the universe.

What is Copernicus contribution to astronomy quizlet?

Nicolaus Copernicus was an astronomer who discovered that the Sun is the center of the universe (Heliocentric Theory) and the planets and stars revolved around it. … He thereby created a concept of a universe in which the distances of the planets from the sun bore a direct relationship to the size of their orbits.

What are the major contributions of Copernicus?

Nicolaus Copernicus (1473 – 1543) was a Polish astronomer who is most famous for his contribution in establishing the heliocentric nature of the Solar System. His theory led to the Copernican Revolution, which is considered as the launching point of modern astronomy and the Scientific Revolution.

What was one of the contributions made by Galileo to astronomy?

Galileo refined the concept of a telescope and was able to make telescopes with more than 30x magnification. He used his telescope to make significant discoveries. Perhaps the most significant discovery at the time was the four major moons of Jupiter, Io, Europa, Ganymede and Callisto.

What was Brahe’s contribution to astronomy?

What is Galileo’s contribution to the Copernican Revolution group of answer choices?

Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons).

What is the contribution of Ptolemy in astronomy?

Ptolemy made contributions to astronomy, mathematics, geography, musical theory, and optics. He compiled a star catalog and the earliest surviving table of a trigonometric function and established mathematically that an object and its mirror image must make equal angles to a mirror.
