What is one of kepler's laws of planetary motion?

The Kepler laws of planetary motion are:

1) The planets revolve around the Sun following elliptical orbits, in which the Sun occupies one of the two focii

2) A line segment connecting the Sun with the center of each planet sweeps out equal areas in equal intervals of time --> this means that the speed of the planet changes according to its distance from the Sun: the closer to the Sun, the faster the planet

3) The square of the orbital period of the planets is proportional to the cube of the semi-major axis of the orbit. In formula

and the constant in the equation has the same value for every planet orbiting around the Sun.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
