Io: A Volcanic Puzzle – NASA Solar System Exploration
WEBNov 9, 1995 · On 7 December 1995, Galileo will have its one and only opportunity for a close encounter with Jupiter's moon Io, the most volcanically active body in the solar system. Io looks remarkably different from any other moon in the solar system, let alone any of Jupiter's other moons: there's nothing else in the solar system that looks like a planet ...

In Depth | Triton – NASA Solar System Exploration
WEBTriton is the largest of Neptune's 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet's rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by …
In Depth | Europa – NASA Solar System Exploration
WEBJupiter’s moons Io, Europa, and Ganymede are in what is called a resonance – every time Ganymede orbits Jupiter once, Europa orbits twice, and Io orbits four times.
Io Observer - NASA Solar System Exploration
WEBOct 1, 2024 · The Jovian moon Io is likely the most geologically active body in the solar system, offering insight into tidal heating, volcanic processes, and other phenomena. However, its location within Jupiter''s radiation belt presents significant engineering challenges that must be addressed to enable future missions to Io.

In Depth | Earth's Moon – NASA Solar System Exploration
WEBThe brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has …
In Depth | Earth – NASA Solar System Exploration
WEBWith a radius of 1,080 miles (1,738 kilometers), the Moon is the fifth largest moon in our solar system (after Ganymede, Titan, Callisto, and Io). The Moon is an average of 238,855 miles (384,400 kilometers) away from Earth. That means 30 Earth-sized planets could fit in between Earth and its Moon. Rings. Rings. Earth has no rings. Formation ...
