Fun facts about io moon8/17/2023 ![]() No human missions are planned as yet, due to the extreme radiation environment and highly toxic atmosphere and surface. Robotic missions to Io could study its volcanism in closer detail.It is the most volcanically active object in the solar system. Io is the third largest of Jupiters moons and very similar in size to our own moon. It orbits Jupiter at an average distance of 262,000 miles (422,000 km,) similar to the distance the Moon orbits Earth. It orbits Jupiter at an average distance of 262,000 miles (422,000 km,) similar to the distance the Moon orbits Earth. Ganymede is the largest moon in the Solar System Ganymede is the only moon to have a magnetosphere CALLISTO FUN FACTS. Io is the fifth moon in distance from the planet Jupiter. Io is made mostly of silicate rocks, and its surface is painted with sulfur particles from the volcanoes and frosts that are created as the atmospheric gases freeze out and fall to the ground. Moons The Sun Asteroid Belt Comets Solar System Io Moon Facts The colorful Jupiter moon Io, the most volcanically active body in the solar system Io is the fifth moon in distance from the planet Jupiter.The average height of Io’s peaks are around 6 km. Io has a number of mountains, some of which rise up as high as Mount Everest on Earth.The volcanic plumes of Io rise up as high as 200 km, showering the terrain with sulfur, sulfur dioxide particles, and rocky ash.Some of the material becomes part of a ring of charged particles around Jupiter called the Io plasma torus. Gases from the atmosphere escape to space at the rate of about a ton per second. Io has a very thin atmosphere that contains mostly sulfur dioxide (emitted from its volcanoes).It is covered in volcanoes, more than 100 of which. Io even has lakes of molten silicate lava on its surface. NASA’s Voyager 1 spacecraft took the first close up pictures of Io in 1979. The moon Io is the most volcanically active world in the solar system. The volcanoes of Io are constantly erupting, creating plumes that rise above the surface and lakes that cover vast areas of the landscape. There is a moon that belongs to Jupiter, Io, that may be one of the most volatile places in our solar system. But it turns out, these scientists were dead wrong about Io.The volcanism on Io is due to tidal heating, as the moon is stretched by Jupiter’s strong gravitational pull and by the lesser gravitational effects of the other satellites.They make this little moon the most actively volcanic world in the solar system. Io has more than 400 active volcanoes on its surface.Jupiter’s Galilean moons size comparison ( Io, Europa, Ganymede and Callisto) Facts about Io Fast Summary Facts About The Moon lo Discovered: January 8th, 1610 by Galileo Galilei Name: Named after the Greek mythological lover of Jupiter Size.
