SOLAR SYSTEM

Detailed explanation-1: -The most massive of the moons are the four Galilean moons: Io, Europa, Ganymede, and Callisto, which were independently discovered in 1610 by Galileo Galilei and Simon Marius and were the first objects found to orbit a body that was neither Earth nor the Sun.

Detailed explanation-2: -Astronomers still refer to the four moons as the Galilean satellites in honor of their discoverer. The German astronomer Johannes Kepler suggested naming the satellites after mythological figures associated with Jupiter, namely Io, Europa, Ganymede, and Callisto, but his idea didn’t catch on for more than 200 years.

Detailed explanation-3: -ESA Science & Technology-Jupiter’s largest moons From top to bottom, the moons are Io, Europa, Ganymede and Callisto. Europa is almost the same size as Earth’s moon, while Ganymede, the largest moon in the Solar System, is larger than planet Mercury.

Detailed explanation-4: -Jupiter’s 4 largest moons exhibit some of the most interesting geology in the solar system. They were discovered by Galileo Galilei and are known as the Galilean moons. Jupiter’s largest moon, Ganymede, is larger than Mercury while the other three are larger than Pluto.

Detailed explanation-5: -On January 7, 1610, Italian astronomer Galileo Galilei discovered, using a homemade telescope, four moons orbiting the planet Jupiter. Looking at what he thought were a group of stars, he realized the objects appeared to move in a regular pattern.

Detailed explanation-6: -Four of Jupiter’s moons: Io, Europa, Ganymede and Callisto-known as the Galilean moons-were the first celestial objects to be discovered orbiting an object other than the sun or Earth when Galileo Galilei first observed them in 1610.
