He discovered Saturn's biggest moon, Titan, and was the first to explain Saturn's strange appearance as due to "a thin, flat ring, nowhere touching, and inclined to the ecliptic." [10] In 1662, he developed what is now called the Huygenian eyepiece, a telescope with two lenses to diminish the amount of dispersion. [11]
Saturn is named after the Roman god of wealth and agriculture, who was the father of the god Jupiter.Its astronomical symbol has been traced back to the Greek Oxyrhynchus Papyri, where it can be seen to be a Greek kappa-rho ligature with a horizontal stroke, as an abbreviation for Κρονος (), the Greek name for the planet ().

The Huygens probe, supplied by the European Space Agency (ESA) and named after the 17th century Dutch astronomer who first discovered Titan, Christiaan Huygens, scrutinized the clouds, atmosphere, and surface of Saturn's moon Titan in its descent on January 15, 2005. It was designed to enter and brake in Titan's atmosphere and parachute a fully ...
But some of the voluminous data gathered by Cassini during its 13 years of surveying the Saturnian system is only now being fully examined. ... "Titan's seas are pulled by Saturn's massive gravity ...
This departure is due to the mini moon being overwhelmed by the stronger tug of the sun's gravity. However, it will come closer for a quick visit in January, at which time Nasa will use a radar ...
"The two giant planets will appear just a 10th of a degree apart - that's about the thickness of a dime held at arm's length," NASA explained. Get your telescope ready: Jupiter, Saturn to shine ...
Mimas, also designated Saturn I, is the seventh-largest natural satellite of Saturn.With a mean diameter of 396.4 kilometres or 246.3 miles, Mimas is the smallest astronomical body known to be roughly rounded in shape due to its own gravity.
Together with his previous two discoveries, Cassini named these satellites Sidera Lodoicea. In his work Kosmotheôros [16] (published posthumously in 1698), Christiaan Huygens relates "Jupiter you see has his four, and Saturn his five Moons about him, all plac’d in their Orbits."
