What is meant by planetary motion?
Kepler’s three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.
What are the three laws of Kepler on planetary motion?
There are actually three, Kepler’s laws that is, of planetary motion: 1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its …
How did Kepler impact the world?
Tycho’s data let Kepler refine his model for planetary motion. It led him to create what we today call Kepler’s three laws of planetary motion. The first law of planetary motion states: Planets move around the sun in an elliptical orbit, where the sun is one of the foci.

What did Ptolemy discover?
What were Ptolemy’s achievements? Ptolemy made contributions to astronomy, mathematics, geography, musical theory, and optics. He compiled a star catalog and the earliest surviving table of a trigonometric function and established mathematically that an object and its mirror image must make equal angles to a mirror.

When did Galileo work?
From 1589 to 1610, Galileo was chair of mathematics at the universities of Pisa and then Padua. During those years he performed the experiments with falling bodies that made his most significant contribution to physics.
