Kepler's laws are about the planets' orbits.
The first law says that the orbit of any planet around the Sun is an ellipse with the Sun at one of the focii.
The second law states that the line joining the Sun to a planet covers equal area in equal intervals of time.
The third law states the square of the time period of the planet is proportional to the cube of the semi-major axis of its elliptical orbit.
Kepler's law explained planetary motion, but nothing other than motion, and really no one could properly explain why Kepler's law worked. So therefore we move on to Newton's first law.

∙ 8y agoNothing definite, only that they fitted the latest measurements made by Tycho Brahe with unprecedented accuracy.
But 80 years later, after the discovery of the law of gravity and the laws of motion, Kepler's theory was found to be consistent with the new theories to a high degree of accuracy.

∙ 8y agoNo. Kepler developed the laws of planetary motion.

∙ 10y agoKepler used measurements made by his employer, Tycho Brahe, which were more accurate than had ever been achieved before.

What was Johannes Kepler's nickname?
1. planets travel in elliptical orbits around an off-centre sun. 2. the speed of a planet's orbit depends on its distance from the sun. when a planet's close to the sun it, orbits faster. when it's further away from the sun, it travels slower 3. the farther a planet or dwarf planet is from the sun, the longer its orbit *note: did this because there weren't any fricken answers on the web that was specific, easy and in point form answer. Have fun!!!!! (you probably won't) lol :P
What conclusion did Kepler eventually come to that revolutionized the heliocentric model of the solar system?
kepler determined the planetary orbits were elliptical
What did Thyco Brahe study?
Mostly, his eyes and pen. He also used azimuth circles that circumscribed his observatory at Uraniborg to assist him in accurately plotting the movements of the stars, planets and other celestial objects. Brahe also built a sextant many times larger than any that had been built before, increasing it's accuracy notably. No previous observer had ever recorded so many detailed positions of objects in the heavens.
Which is not one of Newton's laws?
A) What goes up must come down. The three laws Sir Isaac Newton's three laws of motion describe the motion of massive bodies and how they interact. While Newton's laws may seem obvious to us today, more than three centuries ago they were considered revolutionary. What Are Newton's Three Laws of Motion? Newton's First Law of Motion (Law of Inertia) Newton's Second Law of Motion (Law of Mass and Acceleration) Newton's Third Law of Motion
What source does kinetic energy come from?
Motion. The motion can be energized by virtually any source of energy.
Would Johannes Kepler have been as successful as he was if Brahe had not come before him?
Johannes Kepler
What is use of Johannes Kepler's invention telescope?
A telescope is used to magnify things that are far away.That said, I'm not sure who told you that Johannes Kepler invented the telescope. He didn't invent the telescope itself, but he did come up with a new design. Kepler's design uses a convex lens at the eyepiece rather than a concave one. This has several advantages, but a couple of disadvantages, such as the image appearing upside down. This makes it largely useless for terrestrial work, but it's suitable for astronomy, which is what Kepler was interested in anyway.
Who was Johannes Kepler mentor?
He did his best work with Tycho Brahe who was a Danish nobleman who employed Kepler as a mathematician, a fairly junior appointment. Tycho tended to keep his measurements secret, to retain control, but after his death Kepler was able to to get full access and then produced his famous three laws of planetary motion.
Where Did Isaac Newton come up with the three laws of motion?
Isaac Newton thought of the three laws of motion while watching an apple fall from a tree.

How does the gravity of Kepler compare to the gravity on earth?
There is no single planet named Kepler. Rather, the Kepler label is added to the designations of planets discovered using the Kepler telescope. Planets discovered in this way are given designations such as Kepler-20f and Kepler-87c. There are more than 1,000 of these planets that come in a wide range of masses and a wide range of surface gravities.
When were elliptical orbits discovered?
1602 AD by Johannes Kepler. Kepler gave us the orbital law of the Earth orbiting the Sun in an ellipse. The Law states , that Earth sweeps equal arcs of the orbit in equal times. The Sun is at one of the foci of the ellipse, not the centre. The other foci might be termed as a 'blind' focus; nothing there. It has subsequently been found that the planets, Earth included, do not orbit in a closed ellipse, but in an Ellipsoid. An ellipsoid is the track were the planet 'overshoots' its starting point on its previous orbit. Al the planets and the natural satellites (moons) do this in there respective ellipsoidal orbits.

How did humanism effect Johannes Kepler's work?
Humanists like to think of the universe as a cohesive whole, and believe that everything has a reason. This belief caused Kepler to try to come up with holistic interpretations of astronomical truths, so, even though he gathered a lot of empirical evidence, much of his work that we ignore in modern times was speculation on the structure of the universe. For example, he was pretty excited to come up with a theory based on geometric structures and how they fit in with the orbit of the planets. Look up Kepler's Polygons. It makes a nice picture, but it later turned out to be wrong. Kepler also refused to use the Copernican system (though he was okay with the Tychonian system, apparently?) because having the sun in the center of the universe messed up his perception of the natural order of things. All in all, Kepler refused to publish anything unless it fit in with his humanistic perceptions. He did end up finishing Tycho Brahe's planetary charts, though.
