What are the name of Galilean moons?

Discovery of Galilean Moons
The Moon of Jupiter which is also known as the Galilean Moons and individually it is known as the Galileans have taken their names from the great astronomer Galileo Galilee of Italy. He discovered them in 1610 between 7 to 13 January.
He described these Galileans at his time as the ‘Three fixed Stars’ which are not visible due to their smallness using his own made ‘Telescope’ now it has been repaired and stored in the Museum. All three of these space objects are very close to Jupiter and are aligned in a straight line.

The research of Galileo told that their position is changing as far as the concern with the behavior of stars which was an inexplicable statement.
Galileo was in an illustration of it and hence he again researched it and on 10 January he noticed that one of them had disappeared and the reason behind this was that a particular object was hidden behind Jupiter. And after a few days of completing his observation, he told that actually they are not stars and they are orbiting Jupiter and hence they are in fact Moons of Jupiter. And by the 13 January, he had discovered a fourth Moon and named them as Medicean stars.
