3 laws of plantery Motion
the ration of the squares of the revolution periods for 2 planets is equal to the rationof cubes of their semimajor axes
the line joining the planet with to the sun sweeps out=areas in equal timesas the planet travels around the ellips
the orbits of the planets are ellip, with the sun at one focuse of the ellips
defined ellips in terms of distances
Planets aren't circles but it is flattented circles
Tyco Braha(1546-1601)
measured parallax
stars were so fare to measure their parallax
observations about supernova
observation about Mars helped later
used modern instruments before telescope
Copericn(1473-1543)
explained the existence of empty space(vacum)
explained the brightness of the planets
retrigrade motion can be explained in terms of geometry
aren't always the same distatance from the earth
earth is just a planet
earth is rotated once in24 hours
moon oribits around the earth
sun is the centre of the univers
