Active moon

Looking at the long term, our Earth is a very active planet. Many geographical activities still change the appearance of our planet today. There are many volcanoes in the dormant phase, but we are never sure when they will erupt. However, the Earth is not even close to the most active bodies in our solar system. When we think of restless, active planets – we all think of Venus. Yes that is correct. However, the most geologically active object in our solar system is Jupiter’s moon Io.

Together with the other three moons of Jupiter (Europe, Callisto, Ganymede), Io the moon was discovered by Galileo Galilei in 1610. With an average distance of 421,700 km. Io is the closest moon to Jupiter. It is possible that because of this, (unlike the other three) Io has no water for a month.

Io moon

Io the moon has a weak atmosphere of sulfur dioxide. That is why we see the surface of this Jupiter moon. Although, there are mountains on the Io to 10 kilometers high, it is not possible to map the surface of the Io. This is due to constant geological activities. Many active volcanoes are constantly changing the appearance of the Io surface. Therefore, photos obtained from the Voyager 1 and Voyager 2 spacecraft confirm this claim. The surface of the Moon is rapidly changing. Io is positioned as the most active object in our solar system. While passing close to the Io, the New Horizons spacecraft sent an extremely well-recorded volcanic eruption on the Io to Earth.
