Newton's law of universal gravitation can be used to show that all planets orbit the sun in an elliptical path. Each planet also has gravity and keeps their own moons orbiting around them also in elliptical orbits.
Saturn!
Saturn was the first planet discovered to have rings. They were first observed by Galileo Galilei in 1610 through his telescope.
Galileo first observed the planet Mercury through his telescope in 1610.
Galileo discovered Jupiter's four largest moons, including Io, Europa, Ganymede, and Callisto, in 1610. He observed them using a telescope, marking the first time celestial bodies were discovered that did not orbit Earth.
Galileo discovered the moons of Jupiter and observed the phases of Venus, providing evidence to support the heliocentric model of the solar system. Herschel discovered the planet Uranus and infrared radiation, expanding our understanding of the universe.

Jupiter/ The three other major moons of Jupiter are Io, Callisto, and Ganymede. There are many more natural satellites (Moons) around Jupiter. The four named in this answer are known as the Galilean Satellites, because Galilieo was the first to see them, through his invented telescope. Telescopes prior to Galileo's telescope, either didn't exist, or were very primitive.
Neptune was discovered in 1846. Though it was first observed in 1612 by Galileo Galilei.
