There are four Galilean moons, so named because they were discovered by Galileo. They are comparartively large compared to the other Jovian moons, so they were visible from Earth as companions to the planet. They are Ganymede, Callisto, Europa, and Io.
There is no direct connection between the mass of a planet and the number of moons it has. Mars is less massive than Earth but has twice as many moons as does Earth. Jupiter is more massive than either Mars of Earth and has many more moons that either of them.
Our moon, the earths moon, is the fifth largest moon in the solar system. Ganymede is the largest moon (a moon of Jupiter), then Titan is the second largest (moon of Saturn), then third is Callisto (another moon of Jupiter) and the fourth largest is Io (another of Jupiters moons).
One moon and its called moon.
Jupiter has four moons that orbit it. the names of these moons are IO (eye-oh) Callisto, Europa and Ganymede.Time taken for the moons to orbit Jupiter:IO- 1.7 Earth yearsCallisto- 16.7 Earth yearsEuropa- 3.5 Earth yearsGanymede- 7.1 Earth years
At this time (mid-2014), 67 moons of Jupiter are confirmed. They are all in orbits around the planet. None are 'on' it.
Saturn has 82 moons, the most famous of which is Titan. However, only a few of these moons are large enough to be visible from Earth through a moderate-sized telescope.
There is typically one moon visible in the night sky, also known as Earth's moon. However, there can be rare occasions where two moons are visible due to phenomena like a second moon or a passing satellite.
Vesta does not have any moons. It is one of the largest objects in the asteroid belt located between Mars and Jupiter.
Uranus has 27 moons and Earth has 1 moon.
Pluto has four known moons, four times as many as the Earth.
4 moons could ft inside the Earth.
