Top 10 Incredible Moons of Our Solar System

6. Callisto

Unlike the other famous moon of Jupiter, Callisto does not have any geological activity to coarsen its surface. In fact, this natural satellite is the only body in the solar system whose surface has remained unchanged for the past 4 billion years. The lack of regular resurfacing makes Callisto display a fascinating face, filled with a plethora of craters piling up one on top of each other. In order to get a clue about this phenomenon let’s just say that in some areas you can see concentric rings of craters within craters, a “crater-caption” if you will.

 

7. Triton

Triton is the largest moon of Neptune and surprisingly, it was noticed only about two weeks after the planet itself was discovered. The first thing that has captured attention of the scientists was the fact that this is the largest body to have a retrograde orbit. In other words, it rotates in the opposite direction of Neptune’s orbit, an element that suggests Triton is very likely to be a captured moon. However, the most captivating thing about Triton is the fact that it contains active (ice) volcanoes that are regularly spitting out water and ammonia.

 

8. Dactyl

Space represents the only place where anything is possible and Dactyl stands proof of that. Although the debate still carries on, the fact remains: Dactyl is currently the only natural satellite known to orbit an asteroid (Ida). Ever since its intriguing discovery in 1995, the smallest moon in the solar system has answered some of the important questions about the universe and it showed that even objects as small as Ida can have natural satellites.

 

9. Miranda

Even though Miranda is considered one of the “ugliest” moons in the solar system, the natural satellite of Uranus has one of the most diversified landscapes we came across so far. Because it looks like a bunch of rocks and particles glued together in a hurry, numerous scientists believe that Miranda’s peculiar shape must be the result of a major collision that has torn the surface apart.

 

10. Epimetheus and Janus

Although nowadays they are considered two distinct moons of Saturn, the fact that they share the orbit so close together made astronomers believe that they were the same body a long time ago. However, this is not the thing that makes these little moons so fascinating, but rather the show they put on every four years when they switch places and come very close to each other, almost to the point of collision.
