That's Saturn.
Titan, Dione, Tethys, and Mimas are moons of Saturn.

Saturn has 62 known moons. Of all these moons Titan is the largest (second largest in our solar system.). The next is Enceladus which emits gases and dust. Hyperion which is in resonance with Titan. Phoebe which is the largest of irregular moons.
The seven spherical (major) moons of Saturn, compared to the diameter of Earth's moon, in descending order, are:Titan:......... 148%,Rhea:........... 44%,Iapetus........ 42%,Dione:.......... 32%,Tethys:......... 30%,Enceladus:.... 14%,Mimas:.......... 12%.These are the only moons of Saturn that are massive enough to assume a spherical shape.
I think you're confusing Saturn with Jupiter. Jupiter has four major moons, Saturn has seven. Saturn's moons were disovered by three people. Titan, Saturn's largest moon, was discovered by Christiaan Huygens. Tethys, Dione, Rhea, and Iapetus were discovered by Giovanni Domenico Cassini. William Herschel discovered Mimas and Enceladus. Galileo Galilei discovered Jupiter's four major moons.

Saturn has nine satalites. They are Dione, Enceladus, Hyperion, Iapetus, Mimas, Phoebe, Rhea, Tethys, Titan.

Saturn has over sixty moons, but the largest ones are Titan, Rhea, Iapetus, Dione, Tethys, Enceladus, and Mimas.
At last count, 61; although many of these are small, less than a few miles in diameter. Titan is the largest, and Rhea, Dione, Tethys, Enceladus, Mimas and Hyperion are significantly more prominant than the rest.
The largest 7 are Titan, Rhea, Iapetus, Dione, Tethys, Enceladus, and Mimas. Titan is the second-largest moon in the Solar System with a diameter of 5150 km (1.5 times our Moon). The next 4 are less than half the size of our Moon, and Enceladus and Mimas 12-14% as large.

Saturn has 30 moons, 12 of which are unnamed. The named ones are Pan, Atlas, Prometheus, Pandora, Epimetheus, Jana, Mimas, Enceladus, Tethys, Telesto, Calypso, Dione, Helene, Rhia, Titan, Hyperion, Iapetus, and Pheobe
Mimas and Tethys, both moons of Saturn, have spectacularly large craters which dominate certain views, and rival the Death Star (and maybe inspired it!). Some astronomers have questioned how an impact crater such a large fraction of the moons' diameters did not completely break them apart. Odysseus crater on Tethys is 450km in diameter; Herschel crater on Mimas is about 139km across.
