Before the advent of telescopic photography, eight moons of Saturn were discovered by direct observation using optical telescopes.Saturn's largest moon, Titan, was discovered in 1655 by Christiaan Huygens using a 57-millimeter (2.2 in) objective lens [14] on a refracting telescope of his own design.

Christiaan Huygens discovered Titan in 1655.. The Dutch astronomer Christiaan Huygens discovered Titan on March 25, 1655. [17] [18] [19] Fascinated by Galileo's 1610 discovery of Jupiter's four largest moons and his advancements in telescope technology, Huygens, with the help of his elder brother Constantijn Huygens Jr., began building telescopes around 1650 and discovered the first observed ...
Enceladus is the sixth-largest moon of Saturn and the 18th-largest in the Solar System. It is about 500 kilometers (310 miles) in diameter, [5] about a tenth of that of Saturn's largest moon, Titan. It is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System.
Iapetus (/ aɪ ˈ æ p ə t ə s /) is the outermost of Saturn's large moons. With an estimated diameter of 1,469 km (913 mi), it is the third-largest moon of Saturn and the eleventh-largest in the Solar System. [a] Named after the Titan Iapetus, the moon was discovered in 1671 by Giovanni Domenico Cassini.
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]
The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter 20 new moons were discovered around Saturn Skip to main content
On January 14, 2005, the tiny Huygens probe—an integral facet of NASA’s Cassini mission—floated down through a thick haze and onto a sandy riverbed on the surface of Saturn’s largest moon.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
