formulated the three laws of planetary motion based on the data gathered by Tycho Brahe. Brahe
believed in a model that the sun orbiting the Earth but the other planets orbiting the sun, Kepler
eventually used the data gathered by Brahe to prove heliocentrism and to calculate the orbital
laws.
Johannes kepler
the orbits of the planets are ellipse with the sun at one focus thus formulating his first law of
planetary motion
Law of ellipses
the planet moves faster when it is near the sun and slower when it is far from the sun.
Law of equal areas
made accurate measurements and observations of the position of stars, sun, moon, and the
planets even before the invention of telescope.
Tycho brahe
In simple language, Kepler’s 2nd law means that:
A. Slowly moving planets are close to the sun
B. The sun is the center of the planetary orbits
C. Planets close to the sun have shorter periods than those farther away
D. A planet moves rapidly or moves more rapidly when near the sun than when father away
