Astro Quiz 6: Moon with Active Volcanoes?

Question #6 – What celestial body in our Solar System has the most  active volcanoes?

Answer: Jupiter’s moon Io (pronounced "Eye-oh") is the most volcanically active body in the Solar System. Io is caught between the tidal pull of massive Jupiter and two of Jupiter’s other moons, Europa and Ganymede. Io has large lava lakes, but less water than any other object in the Solar System.
