english: It wasn't till Huygens had two things: He had a good theory of planetary rings and how the solar system operated, and he had better telescopic, more fine-grain data in which he could figure out that as the Earth is going around faster -- according to Kepler's Laws -- than Saturn, then we catch up with it.
non_english: Vse dokler ni imel Huygens dveh stvari. Dobre teorije o planetarnih obročih in delovanju sončnega sistema. Imel je tudi boljši teleskop in natančnejše podatke, iz katerih je lahko ugotovil, da Zemlja kroži hitreje - po Keplerjevih zakonih - kot Saturn, kasneje ga mi dohitimo.
