Which scientist discovered the laws of planetary motion?

It was Kepler who discovered the laws of planetary motion, and Kepler also summed up three major formulas that can calculate the motion period and trajectory of the planets, and he made great contributions to the study of celestial motion.

Kepler, a famous German astronomer, mathematician, physicist and philosopher, discovered the three major laws of motion of the planets on the basis of Tycho's observation of astronomical data, namely the law of elliptical orbit, the law of area and the law of periodicity.

It was Johannes Kepler, who discovered the three laws, namely orbit, area, and period.

The scientist who discovered the laws of planetary motion was Johannes Kepler, a famous German mathematician, physicist and astronomer. He discovered the three major laws of planetary motion: period, area, and orbit.

Although Copernicus.

The planets are correctly observed to revolve around the Sun, but Kepler correctly defined their orbits.

At the age of 27, Kepler became the wealthy astronomer Tycho Brahe.

Tycho Brahe's assistant asked him to define the orbit of Mars. Throughout his life, Brahe collected astronomical observations, which reached Kepler after his death. (Brahe had his own Earth-centered model of the universe, at least in part, because he didn't want Kepler to use them to justify Copernican's theory.)

Through these observations, Kepler discovered that the orbits of the planets follow three laws.

Like many philosophers of his time, Kepler had a mystical belief that the circle was the perfect shape of the universe and that the orbits of the planets must be circular as a manifestation of the divine order. Over the years, he worked to match Brahe's observations of the motion of Mars with a circular orbit.

Eventually, however, Kepler noticed that an imaginary line from the planet to the sun swept an equal area of space in equal time, regardless of the planet's position in its orbit. If you draw a triangle from the position of the sun to the planet at a point in time.

Then plot its position at a fixed time (say 5 hours or 2 days), then the area of that triangle is always the same, anywhere on the track. In order for all these triangles to have the same area, the planets must move faster when they are closer to the Sun and more slowly when they are furthest from the Sun.

This discovery (which later became Kepler's second law of orbital motion.

This led to what would later become Kepler's first law.

Something is realized: the planet moves in an ellipse (a flattened circle), and the sun is in a focal point, off-center.

Kepler's third law.

It shows that there is a precise mathematical relationship between the distance of the planet from the Sun and the time it takes to orbit the Sun. It was this law that inspired Newton.

, he came up with his own three laws to explain why the planets move the way they do.

The scientist who proposed that the orbit of the planet around the sun is an ellipse and other three laws of planetary motion is Kepler, more than 100 years after Newton discovered the law of gravitation, the British physicist Cavendish skillfully used the torsion scale device to accurately measure the gravitational constant for the first time in the laboratory, and was called "the person who measured the mass of the earth" Kepler based on the astronomical data observed by Tycho and summarized the three laws of planetary motion

It was first discovered by the German astronomer and mathematician Kepler, who patiently studied the motion of Mars on the celestial sphere year after year, looking for the laws of Mars' motion, and after many years of repeated calculations, summed up the laws of planetary motion.

Kepler, arguably one of the world's greatest astronomers, was the first to discover the laws of planetary motion.

The astronomer who discovered the laws of planetary motion was Johannes Kepler.

Further information is as follows:

Kepler's laws are the three laws of planetary motion proposed by the German astronomer Kepler. The first and second laws, published in 1609, were summarized by Kepler from astronomer Tycho's observations of Mars' position; The Third Law was published in 1619. These three laws are also known as the law of ellipse, the law of area, and the law of harmony.

Kepler's law is about the motion of the planets around the sun, while Newton's law is more broadly about the motion of several particles due to the gravitational attraction to each other. In the special case of only two particles, one of which is ultra-light than the other, the light particle moves around the heavy particle, just as the planets move around the sun according to Kepler's laws.

Newton's laws allow for other solutions, however, that planetary orbits can be parabolic or hyperbola. This is something that Kepler's law can't. In a situation where one particle is not super-lighter than another, each particle moves around their common center of mass according to the solution of the generalized two-body problem.

This is also something that Kepler's law cannot achieve.

Kepler's laws, either in geometric language or in equations, relate the coordinates and time of the planets to the orbital parameters. Newton's second law is a differential equation. The introduction to Kepler's law involves the art of solving differential equations.

We will lead to Kepler's second law, because Kepler's first law must be based on Kepler's second law.

Kepler's law is the law about the motion of planets discovered by Kepler. In 1609 he published two laws of planetary motion in his New Astronomy, and in 1618 he discovered a third law. Kepler was fortunate to have access to the very accurate astronomical data that the famous Danish astronomer Tycho Brahe had observed and collected for more than 20 years.

Around 1605, based on Brahe's planetary position data, following Copernicus's theory of uniform circular motion, after four years of calculations, it was found that Tycho's observed data had an error of 8' from the calculation, and Kepler was convinced that Tycho's data was correct, so he questioned the "perfect" motion of God (uniform circular motion).

After nearly 6 years of extensive calculations, Kepler came up with the first and second laws, and another 10 years of extensive calculations, the third law. Kepler's laws gave the Aristotelians and Ptolemaics great challenges in astronomy and physics. He asserted that the earth is constantly moving; The orbits of the planets are not epicycled, but elliptical.

The speed at which the planets revolve is unequal. These arguments greatly shook the astronomy and physics of the time. After almost a century of research on the stars and the moon, physicists are finally able to explain the truth with physical theories.

Newton used his second law and the law of universal gravitation to mathematically rigorously prove Kepler's laws and also make people understand the physical significance of them.

The astronomer who discovered the three laws of planetary motion was Johannes Kepler, a prominent German astronomer, physicist, and mathematician.

Kepler discovered the three major laws of planetary motion, which are the law of orbit, the law of area, and the law of period. These three laws can be described as follows: all planets orbit in elliptical orbits of different sizes; In the same time, the area swept by the planetary radius in the orbital plane is equal; The square of the period of the star's revolution is proportional to the cube of its distance from the sun.

These three laws eventually earned him the reputation of "the ruler of the sky."

On the basis of studying the astronomical data recorded by Tycho, Kaisheng Zappuler summarized the three laws of the motion of the stars

So the answer is: Kepler
