| Answer» 225 Questions & Answers Saturn 1. When did we DISCOVER Saturn? We don’t know exactly when ancient observers first recognized what we now call the planet Saturn. Many ancient civilizations were aware of five wandering points of light in the night sky, which were later named for gods of Roman mythology — Mercury, Venus, Mars, Jupiter, and Saturn. These planets were easily observed with the unaided eye. It was not until the time of Galileo, who first looked at the sky through a telescope, that we observed these wandering “STARS” to be other worlds. The planets outside Saturn’s orbit — Uranus, Neptune, and Pluto — were discovered USING more modern telescopes, BEGINNING with the dis- covery of Uranus by William Herschel in 1781. The discovery of each of these outermost plan- ets generate | |
