- Christiaan Huygens discovered the first known moon of Saturn. The year was 1655 and the moon was Titan. Giovanni Domenico Cassini made the next four discoveries: Iapetus (1671), Rhea (1672), Dione (1684), and Tethys (1684). Mimas and Enceladus were both discovered by William Herschel in 1789.

When Was Saturn Discovered Additionally, Saturn’s moons were discovered over a period of time. Christian Huygen discovered Titan, which is Saturn’s largest moon. Giovanni Domenico Cassini discovered four moons – Iapetus, Rhea, Tethys, and Dione. In 1789, the astronomer William Herschel discovered two more moons – Mimas and Enceladus. In 1848, British scientists discovered a moon called Hyperion.

Moons of Saturn It is the second largest moon of Saturn measuring 1,530 km across and is the 9th largest natural satellite in the solar system. Iapetus – With a diameter of 1,470 km, it is the 3rd largest moon of Saturn.It was discovered by Giovanni Cassini in 1671.It has a distinct feature of having a bright and dark hemisphere. Dione – The 4th largest moon of Saturn named after a vague character in Greek Mythology.It measures 1,122 km in diameter and is the 15th largest moon in the solar System. Despite its size, its mass exceeds all the moons smaller than itself combined.ione – The 4th largest moon of Saturn named after a vague character in Greek Mythology.

Hubble finds new Neptune moon: Smallest known moon in the Neptunian system This diagram shows the orbits of several moons located close to the planet Neptune. All of them were discovered in 1989 by NASA's Voyager 2 spacecraft, with the exception of S/2004 N 1, which was discovered in archival Hubble Space Telescope images taken from 2004 to 2009.

Saturn Saturn's largest satellite, Titan, is a bit bigger than the planet Mercury. (Titan is the second-largest moon in the solar system; only Jupiter's moon Ganymede is bigger.) Titan is shrouded in a thick, nitrogen-rich atmosphere that might be similar to what Earth's was like long ago.n 1675, Italian-born astronomer Jean-Dominique Cassini discovered a division between what are now called the A and B rings. It is now known that the gravitational influence of Saturn's moon Mimas is responsible for the Cassini Division, which is 3,000 miles (4,800 kilometers) wide.

- January 7th Galileo actually saw all four moons, but was unable to resolve Io and Europa, which were very close together at the time; he saw them as a single star. While Galileo had built himself the world's finest optical telescope of the time, by today's standards it would hardly qualify as a cheap department-store toy telescope. January 8th Again all four moons were visible, but Galileo was expecting to see only three, so he missed the fourth - Callisto - far to the east of Jupiter away from the three that amazed him because of their movement to the west.

Saturn's Rings and Moons are Solar System Antiques The Cassini spacecraft observes three of Saturn's moons set against the darkened night side of the planet. Saturn is present on the left this image but is too dark to see. Rhea (1,528 kilometers, or 949 miles across) is closest to Cassini here and appears largest at the center of the image.

Science Overview Cassini's observations of Saturn's largest moon, Titan, have given scientists a glimpse of what Earth might have been like before life evolved. They now believe Titan possesses many parallels to Earth, including lakes, rivers, channels, dunes, rain, clouds, mountains and possibly volcanoes.

Rings of Saturn Robert Hooke was another early observer of the rings of Saturn, and noted the casting of shadows on the rings. In 1675, Giovanni Domenico Cassini determined that Saturn's ring was composed of multiple smaller rings with gaps between them; the largest of these gaps was later named the Cassini Division.

List of Neptune's moons Neptune has a total of 14 moons. The largest moon is Triton which was discovered by William Lassell just seventeen days after Neptune was found. One hundred years later the second moon, Nereid was found. The Hubble Telescope found the 14th moon in 2013. Most of Neptune's moons are named after sea nymphs.

- Exploring both Saturn and Titan, Saturn's mysterious moon. Name Christiaan Huygens (1629-1695) was a Dutch scientist who discovered Saturn's rings and, in 1655, its largest moon, Titan.Italian Jean-Dominique Cassini (1625-1712) discovered the Saturnian satellites Iapetus, Rhea, Tethys and Dione.he ESA Huygens probe is the first to land on a world in the outer Solar System-on the surface of Titan, Saturn’s largest moon. Data from Cassini and Huygens may offer clues about how life began on Earth. Launch 15 October 1997 (Titan-IVB/Centaur at Cape Canaveral, United States).

- Pluto has three known moons. Its largest moon, named Charon (KER-ən), is about half the size of Pluto. Astronomers discovered Pluto's two other moons -- Nix and Hydra -- in 2005 using images from NASA's Hubble Space Telescope.Nix and Hydra are very small. Scientists believe the moons are less than 100 miles (160 kilometers) wide.ts largest moon, named Charon (KER-ən), is about half the size of Pluto.

Galilean moons Galilean moons. The Galilean moons are the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto. They were first seen by Galileo Galilei in January 1610, and recognized by him as satellites of Jupiter in March 1610. They are the first objects found to orbit another planet. Their names derive from the lovers of Zeus. They are among the largest objects in the Solar System with the exception of the Sun and the eight planets, with a radius larger than any of the dwarf planets. Ganymede is the ...

- 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 on a refracting telescope of his own design. Tethys, Dione, Rhea and Iapetus (the  Sidera Lodoicea ) were discovered between 1671 and 1684 by Giovanni Domenico Cassini.
