No, they are not.
Europa and Ganymede are two of planet Jupiter's 63 moons!
Europa, Ganymede, and IO :)
Io, Europa, Callista, Ganymede
From Brightest to Dimmest: Ganymede Io Europa Callisto Use JPL's HORIZONS web ephemeris to look up apparent magnitudes of jovian satellites.
Yes there are and the four major ones are lo europa ganymede and callisto
Io, Europa, Ganymede and Callisto are the four satellites that orbit Jupiter.
The four biggest satellites of Jupiter are Ganymede, Callisto, Io, and Europa. Ganymede is the largest moon in the solar system and is even bigger than the planet Mercury. These four moons are known as the Galilean moons, named after Galileo Galilei who discovered them in 1610.
Europa is smaller than Ganymede and Callisto, but larger than Io. Ganymede is the largest moon in the solar system, and Callisto is the second-largest. Europa ranks as the sixth-largest moon in the solar system.
Ganymede is a moon of Jupiter. It is the largest of the four Galilean satellites first observed and noted by Galileo. The other three are Io, Europa, and Callisto.Ganymede is not a planet.
The four satellites are Jupiter's largest moons. They were found by Galileo Galilei. They are Callisto, Europa, Ganymede and Io.
Ganymede orbits the planet Jupiter. It is the largest of the four Galilean satellites first observed and noted by Galileo. The other three are Io, Europa, and Callisto.
Jupiter is a planet whose satellites, particularly Europa, Io, and Ganymede, create significant tidal effects due to their strong gravitational interactions. These tidal forces lead to phenomena such as volcanic activity on Io and potential subsurface oceans on Europa and Ganymede.
Jupiter has 60 satellites but its largest ones are io europa callisto and ganymede
