In Depth | Enceladus – NASA Solar System Exploration
Oct 9, 2008 · Few worlds in our solar system are as compelling as Saturn’s icy ocean moon Enceladus. A handful of worlds are thought to have liquid water oceans beneath their frozen …
In Depth | Titan – NASA Solar System Exploration
The surface of Titan is one of the most Earthlike places in the solar system, albeit at vastly colder temperatures and with different chemistry. Here it is so cold (-290 degrees Fahrenheit or -179 …
In Depth | Saturn Moons – NASA Solar System Exploration
The Saturn system is far outside of the habitable zone, and Titan’s surface temperature is so cold that the moon’s surface is largely water ice instead of rock. But the temperature is just right for …
Planet Compare - NASA Solar System Exploration
Oct 21, 2025 · NASA’s real-time science encyclopedia of deep space exploration. Our scientists and far-ranging robots explore the wild frontiers of our solar system.
In Depth | Tethys – NASA Solar System Exploration
This may be because its proximity to Saturn causes more tidal warming, and that warming kept Tethys partially molten longer, erasing or dulling more of the early terrain.
Because the moon reflects so much sunlight, the surface temperature is extremely cold, about –330 degrees F (–201 degrees C). The surface of Enceladus displays fissures, plains, …
In Depth | Moons – NASA Solar System Exploration
Both have subsurface oceans and Titan also has surface seas of lakes of ethane and methane. The chunks of ice and rock in Saturn's rings (and the particles in the rings of the other outer …

In Depth | Europa – NASA Solar System Exploration
Images from the two Voyagers revealed a surface brighter than that of Earth's moon, crisscrossed with numerous bands and ridges, and with a surprising lack of large impact craters, tall cliffs, …
In Depth | Io – NASA Solar System Exploration
Thus, the surface of Io is constantly renewing itself, filling in any impact craters with molten lava lakes and spreading smooth new floodplains of liquid rock.
