Detailed explanation-1: -Bottom line: You can see Jupiter’s moons – Io, Europa, Ganymede and Callisto, known as the Galilean satellites – with your own eyes with the help of binoculars or a small telescope.
Detailed explanation-2: -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.
Detailed explanation-3: -Use a low magnification, long focal length eyepiece to find and center the object. It will appear as a fairly small, bright dot. You may then increase the magnification with a shorter focal length eyepiece. It will still look pretty small, even at higher magnification.
Detailed explanation-4: -Europa’s surface is made of water ice and so it reflects 5.5 times the sunlight than our Moon does. Europa orbits Jupiter at about 417, 000 miles (671, 000 kilometers) from the planet, which itself orbits the Sun at a distance of roughly 500 million miles (780 million kilometers), or 5.2 astronomical units (AU).
Detailed explanation-5: -The Great Red Spot. Jupiter’s Moons: Io, Europa, Ganymede, and Callisto. An eclipse happens when one of Jupiter’s moons move through Jupiter’s shadow. An occultation happens when one of Jupiter’s moons disappears behind the planet. More items
