Io
The innermost Galilean moon is Io. It's a veritable volcano in space, being stressed by Jupiter's tidal forces.Comment : I think the innermost moon (not just of the Galilean moons) is Metis.
Because they were discovered first by Galileo.
The Galilean moons orbit Jupiter.
The Galilean moons were discovered by Galileo Galilei in 1610.
No. It is a moon of Mars. The Galilean moons are moons of Jupiter.
No. There are four Galilean moons: Io, Europa, Ganymede, and Callisto.
Io is the innermost of the four large moons (Galilean moons) of Jupiter. Its closeness to Jupiter means that its surface is in a constant state of flex, the gravity from Jupiter distorts its surface, generating heat and flaws in the surface of the moon. This means that volcanoes are a common occurrence on Io.
They were discovered by Galileo.
Callisto is composed of rock and ice and is the least dense of the Galilean moons.
The Galilean moons are the four largest moons of Jupiter, so called because they were discovered by Galileo Galilei.
The smallest of the Galilean moons is Amalthea, which is one of Jupiter's moons. It is irregularly shaped and has a reddish color due to its surface composition.
Yes, one of Jupiter's moons is named Io. It is the innermost of the four Galilean moons and is known for its active volcanism, making it one of the most geologically active bodies in the solar system.
