The principal similarity is that both made major contributions to the establishment of the heliocentric model of the solar system – Galileo by making discoveries which were much easier to understand in a heliocentric context, and Kepler by demonstrating that heliocentric (well, heliofocal) elliptical orbits described.
What are the 10 major contributions of Johannes Kepler?
Johannes Kepler’s 10 Major Contributions To Science #1 He was the first to publish a defense of the heliocentric model of Copernicus #2 He discovered that a planet moved at different speeds according to its distance from the sun #3 Johannes Kepler discovered that planets move in elliptical orbits around the sun
What did Tycho Brahe and Kepler discover about Mars?
At the same time Galileo was searching the heavens with his telescope, in Germany Johannes Kepler was searching them with his mind. Tycho’s precise observations permitted Kepler to discover that Mars (and, by analogy, all the other planets) did not revolve in a circle at all, but in an ellipse, with the Sun at one focus.
What did Kepler discover about planets?
Kepler discovered that planets move in elliptical orbits and at different speeds at different times, according to their distance from the sun. Apart from his contributions to astronomy, Kepler laid the foundation of modern optics.
What was Galileo's greatest contribution to science?
Perhaps the most serious critical blows struck were those delivered by Galileo after the invention of the telescope. In quick succession, he announced that there were mountains on the Moon, satellites circling Jupiter, and spots upon the Sun.
What was the connection between Kepler and Galileo?
Kepler was one of the few vocal supporters of Galileo's discoveries and the Copernican system of planets orbiting the Sun instead of the Earth (basically provided the facts that proofed the theory).
What did Kepler and Galileo contribute to the heliocentric model?
The principal similarity is that both made major contributions to the establishment of the heliocentric model of the solar system - Galileo by making discoveries which were much easier to understand in a heliocentric context, and Kepler by demonstrating that heliocentric (well, heliofocal) elliptical orbits described ...
What did Kepler and Galileo do?
illustrious scientists were working in co-operation. There were two such occasions: in 1610, when Galileo discovered the satellites of Jupiter and Kepler supported him, and in 1619, in the so-called three-comet affair, when the two eminent astronomers held opposing positions.
What are Kepler's contributions?
Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He gave three fundamental laws of planetary motion. He also did important work in optics and geometry.
How did Kepler support the heliocentric theory?
Kepler's findings supported the heliocentric theory by demonstrating conclusively that the planets must rotate around the Sun, rather than all bodies in the Solar System rotating around the Earth, as was previously thought.
In what way was Kepler's telescope an improvement over Galileo's telescope?
Kepler improved upon Galileo's design by using a convex lens for the eyepiece instead of a concave lens, as Galileo used. This allowed for a wider field of view and greater magnification, however the images were inverted, so anything observed through the telescope was upside down.
What did Kepler observe that led Galileo in particular to hypothesize that there were stars outside of our solar system?
Galileo's observations showed that these were not clouds but actual features of the Sun, and that the Sun rotates; this confirmed a dramatic prediction made by Kepler in 1609. Showed that the Milky Way actually consists of countless numbers of stars instead of being nebulous.
What is Johannes Kepler known for?
Johannes Kepler is best known for his three laws of planetary motion. These laws are: Planets move in orbits shaped like an ellipse. A line between a planet and the Sun covers equal areas in equal times.
How did Kepler's discoveries contribute to astronomy?
Using the precise data that Tycho had collected, Kepler discovered that the orbit of Mars was an ellipse. In 1609 he published Astronomia Nova, delineating his discoveries, which are now called Kepler's first two laws of planetary motion.
How did Kepler contribute to the scientific revolution?
Though Kepler is best known for defining laws regarding planetary motion, he made several other notable contributions to science. He was the first to determine that refraction drives vision in the eye, and that using two eyes enables depth perception.

What did Kepler add to Copernicus heliocentric?
He is most famous for his improvement to the earlier model of Copernicus by introducing the idea that the planets move in elliptical, rather than circular, orbits and that their movements in these orbits are governed by a set of laws, which became known as Kepler's laws of planetary motion.
Who developed the heliocentric model?
This theory was first proposed by Nicolaus Copernicus. Copernicus was a Polish astronomer. He first published the heliocentric system in his book: De revolutionibus orbium coelestium , "On the revolutions of the heavenly bodies," which appeared in 1543.
Who invented the heliocentric model?
Nicolaus CopernicusNicolaus 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.
Who supported the heliocentric model?
GalileoGalileo supported the heliocentric (Sun-centered) theory of Copernicus. Galileo believed that his new invention, the astronomical telescope, could help him prove that the Sun was the center of our solar system and that Earth was just one of many planets orbiting our star.
