Several astronomers wrote theories of planetary motion. Ptolemy's theories date to antiquity. Copernicus wrote his theories in the early 16th century. Kepler's theories were written in the early 17th century.
Kinetic Theory.
In chemistry, KMT stands for Kinetic Molecular Theory. It is a theory that explains the behavior of gases in terms of the motion of their particles. It states that gases are made up of a large number of small particles that are in constant, random motion.
P-particles (All matter is made up of particles)I-identical (All particles in one substance are identical)S-spacing (There is different spacing between particles of different substances)A-attraction (Particles have a certain attraction to one another depending on the state)M-movement (Particles are in constant motion)
Kinetic molecular theory assumes that gases consist of particles (atoms or molecules) in constant random motion. It also assumes that gas particles are small compared to the distance between them. Additionally, the theory assumes that gas particles are in continuous, rapid, and random motion.
are small, point-like particles that are in constant random motion, and have perfectly elastic collisions with each other and the container walls. Additionally, they have negligible volume compared to the volume of the container in which they are enclosed.
Kepler
Johannes Kepler was born in Germany in 1571 and was a mathematician, astrologer and astronomer. He was best know for his laws of planetary motion which were the foundation for Newton's theory of universal gravitation.

Johannes Kepler, a German mathematician and astronomer, formulated three laws of planetary motion, which described the motion of planets around the sun. These laws provided the foundation for Isaac Newton to develop his law of universal gravitation.
Isaac newton discovered the three principles of planetary motion
There are numerous theories of planetary motion. Ptolemaeus (earth in the centre), Copernicus (the sun in the centre, planets orbit around it), Kepler (planet orbits are ellipses) all wrote such theories.
Well, seeing as he was a Mathematician and Astronomer, he is closely related to the Solar System. During the Scientific Revolution of the 17th century Johannes Kepler discovered and documented the laws of planetary motion. His studies also laid the groundwork for Isaac Newton's theory of universal gravitation.
Johannes Kepler was the scientist who included three laws of planetary motion as part of his heliocentric theory of the universe. These laws, known as Kepler's Laws of Planetary Motion, describe the orbits of planets around the Sun.
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.
He didn't alter them. He showed that his theory of planetary motion under gravity was consistent with them.
Descartes created the most popular theory on planetary motion. He also contributed to the theories and laws of motion as well as the laws of nature.
