I've heard of the other one sooo much....
thnx.
A little bit more on that...
The first law is that planets' orbits are ellipses
The second is more complex. In short, a line connecting the planet and the Sun sweeps out equal areas in equal units of time. This basically refers to that planets move faster closer to the perihelion (closest point to the Sun) and slower closer to the aphelion (furthest point from the Sun).
