Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.
Kepler's law that describes how fast planets travel at different points in their orbits is called the Law of Equal Areas. This law states that a planet will travel faster when it is closer to the Sun and slower when it is farther away, so that the area it sweeps out in a given time is the same regardless of its distance from the Sun.
Gravity is what keeps the planets orbiting round the Sun instead of disappearing off into outer space. We feel a constant gravity force - our weight - holding us down on the Earth's surface. Isaac Newton was the first one to postulate a gravity force that depends on distance. His idea was a force acting on each planet that varied with the inverse square of the planet's distance from the Sun. He was able to prove that if this was the law of gravity in the solar system, then the planets' orbits must follow Keplers' three laws. Kepler formulated his laws from Tycho Brahe's observations of the planets' positions, but it was many years later that Newton came up with the theory that confirmed these laws. People then realised that Keplers' laws and Newton's laws of motion and the law of gravity were all part of one big theory that all stacked up, and that is what we still believe today.
Legend says that newton answered the 2 questions "why do objects fall toward Earth? and What keeps the planets moving in the sky?" by watching an apple fall from a tree. He knew an unbalanced force made it fall, and the same unbalanced force acted on the moon,which keeps it orbiting the Earth. He said these were the SAME force-gravity.
Kepler's Laws of Planetary Motion:1] Each planet moves in an elliptical orbit with the sun at one focus2] The line form the sun to any planet sweeps out equal areas of space in equal time intervals3] The squares of the times of revolution (days, months or years) of the planets are proportional to the cubes of their average distances from the sun.
Known for his eponymous laws of planetary motion.
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".
The rules summarizing planetary movements are called Kepler's Laws of Planetary Motion. These laws were formulated by the astronomer Johannes Kepler in the early 17th century and describe the orbits of planets around the Sun.
Distance from the body and the mass of the body. See Keplers laws of planetary motion for more info.
April 27, 4977 B.C. That was when he once calculated that the universe began. Or, you may mean when he published his Laws of Planetary Motion. He published his first 2 laws in 1609 and his 3rd law around 1619.
Based on our current understanding of gravity, the amount of visible matter (stars and nebulae and whatnot) only accounts for a small amount of the mass that we have mathematically calculated is present in the galaxy (Keplers laws are used for these calculations, the rotation of the milky way actually stays relatively constant unlike that of solar system bodies). As a result, scientists assume that, since there is little evidence that the theory of gravity is wrong, the galaxy must consist of matter that does not produce light, hence the term "dark matter." WIMPS and MACHOS are considered candidates for dark matter, but nobody really knows what it is... yet.
Johannes Kepler (1571-1630), a German who travelled to Prague to become the assistant of Brahe, was studying the orbit of Mars and while examining that data discovered the Laws of Planetary Motion which state an elliptical orbit rather than a circular one.
because kepler was smart
In Kepler's laws of planetary motion, m1 and m2 represent the masses of two objects (usually the Sun and a planet) that are orbiting around each other. Kepler's laws describe the relationship between the orbit of a planet and the mass of the objects involved.

Newton derived Keplars findings from Newton's Theory of Gravity. Thus, newton 'explained' the basis for Keplars findings and extended them.
his hobbies are probably acting, and eating
