What else can I help you with?
Kepler accurately described the motions of all the known planets True or false?
True. Kepler's laws apply to all objects orbiting the sun, even those that had not yet been discovered during his lifetime.
Who analyzed the motions of planets?
Tycho Bache and Johannes Kepler. Tycho watched and records tons of data of the moments of planets, but his assistant, Johannes Kepler analyzed it all and made theories about the movements to better understand them (this was after Tycho passes away).
Who described the orbit of the planets as elliptical?
Johannes Kepler did that first.
What type of orbit did Kepler say planets moved around the Sun in?
Kepler described the orbits of planets around the Sun as an ellipse with the Sun at one of the two foci.
How do the planets periods relate to their distances from the sun?
The relationship is described by Kepler's Third Law.
What were the names of Johannes Kepler's peers?
Kepler's "running mate" would have to be Tycho Brahe. It was Brahe whose work (observations) Kepler used as a springboard to think about the motions of the planets and what mechanism could make them appear to do the things they did.
Why do planets have circular and elliptical motions in the solar system?
The scientific explanation lies in Kepler's laws of planetary motions, which were discovered by Newton to be linked with the law of gravity. All the planets have elliptical orbits, and many of those are close being circular.
Astronomer who discovered that planets orbit the sun in an ellipse rather than a perfect circle?
Johannes Kepler
What are the three laws of Johannes Kepler all about?
Kepler's three "laws" of planetary motion constitute Kepler's explanation of the motions of the inner six planets of the solar system. He formulated them from years of sweating over the notebooks kept by another individual who spent his life watching the planets and keeping records of their motions. (Tycho Brahe). After Kepler's death, Isaac Newton developed his theory of gravity. Anybody who has enough geometry and calculus to give Gravity a good massage can show mathematically that IF gravity works the way Newton suggested it does, then the planets MUST move in the ways described by Kepler's Laws ... a nice confirmation of the work of both Newton and Kepler. These laws not only do a good job of describing how the planets move, but when we use Kepler's and Newton's formulas to figure out how to aim artificial satellites, Apollo capsules, and interplanetary probes to the outer solar system, those things always go where we want them to go ... more nice confirmation of the same theories. Oh yes. That's right. Both of them are "just theories".
Do we use Kepler's Model in modern astronomy?
Yes, Kepler's laws of planetary motion are still used in modern astronomy to describe the motion of planets and other celestial bodies in our solar system. Kepler's model provides a foundation for understanding orbits and predicting the positions of planets accurately.
Did Johannes Kepler discover any planets?
Johannes Kepler did not discover any planets, but he developed the laws of planetary motion which described the movement of planets around the Sun in elliptical orbits. These laws were crucial in advancing our understanding of the motion of celestial bodies.
Kepler discovered that planets move faster when they?
Kepler discovered that planets move faster when they are closer to the sun in their elliptical orbits. This relationship is described by Kepler's second law of planetary motion, which states that a planet sweeps out equal areas in equal times as it orbits the sun.
