No object other than Earth is known to have life. Europa, one of the moons of Jupiter, appears to have liquid water beneath its surface. Scientists speculate that this subsurface ocean might have life.
Ganymede is the largest Jovian moon in our solar system. It is larger than the planet Mercury and has its own magnetic field.
A moon of Jupiter is called a Jovian moon.
All four Jovian planets in our solar system have multiple moons.
Titan
No there are hundreds thanks to the Jovian planets.
Unlike Earth's moon and Mercury, the Jovian moons are subject to very strong tidal forces that heat their interiors.
The Jovian moon Io is 2,263 miles in diameter.
The moon that has the best chance of supporting life is Europa, one of Jupiter's moons. Europa has a subsurface ocean beneath its icy crust that may contain the right conditions for life to exist, with the possibility of hydrothermal vents providing energy sources. NASA's Europa Clipper mission aims to study this moon further for signs of life.
Europa is a moon of Jupiter, making it a part of the jovian planet system. It is not a planet itself but rather a satellite that orbits a gas giant. Europa is an icy world with a subsurface ocean that is believed to have conditions suitable for life.
No, not all jovian planets have active volcanoes. For example, Jupiter and Saturn do not have active volcanoes. However, some of the moons that orbit these planets, such as Io (a moon of Jupiter), do have active volcanoes.
Ganymede is the largest Galilean moon, the largest Jovian moon, and the largest moon in the solar system.
The large Jovian moon thought to have been captured into its present orbit is Triton, which orbits Neptune. Triton's retrograde motion and unique characteristics suggest it was once a Kuiper Belt object that was captured by Neptune's gravity.
