In Depth | Titan – NASA Solar System Exploration
Saturn's largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere. Titan is the second largest moon in our solar system. Only Jupiter's moon Ganymede is larger, by just 2 percent. Titan is bigger than …
In Depth | Europa – NASA Solar System Exploration
Jupiter’s large Galilean moons – Io, Europa, Ganymede, and Callisto – likely formed out of leftover material after Jupiter condensed from the initial cloud of gas and dust surrounding the sun, early in the history of the solar system.

Hydrated Salt Minerals on Ganymede's Surface: Evidence of an …
May 25, 2001 · Reflectance spectra from Galileo's near-infrared mapping spectrometer (NIMS) suggests that the surface of Ganymede, the largest satellite of Jupiter, contains hydrated materials.
In Depth | Jupiter – NASA Solar System Exploration
These four moons are known today as the Galilean satellites, and they're some of the most fascinating destinations in our solar system. Io is the most volcanically active body in the solar system. Ganymede is the largest moon in the solar system (even bigger than the planet Mercury).
Cassini Data Show Ice and Rock Mixture Inside Titan
Mar 10, 2010 · The finding, to be published in the March 12 issue of the journal Science, shows how Titan evolved in a different fashion from inner planets such as Earth, or icy moons such as Jupiter's Ganymede, whose interiors have split into distinctive layers.
Io: A Volcanic Puzzle – NASA Solar System Exploration
Nov 9, 1995 · Io's insides are heated instead by a tidal interaction process between Io, Jupiter and two other moons of Jupiter named Ganymede and Europa. Because Ganymede and Europa gravitationally tug on Io, Io's orbit around Jupiter is not perfectly circular.
In Depth | Triton – NASA Solar System Exploration
Triton 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 Neptune's gravity millions of years ago.
NASA Planetary Science Highlights: 2021
Dec 23, 2021 · On June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s ice-encrusted moon Ganymede than any spacecraft in more than two decades. Less than a day later, Juno made its 34th flyby of Jupiter. This animation provides a “starship captain” point of …
