- In Depth | Europa – NASA Solar System Exploration
The similarities don’t end there Each planet in the inner solar system is less dense than its inner neighbor – Mars is less dense than Earth, which is less dense than Venus, which is less dense than Mercury The Galilean moons follow the same principle, being less dense the farther they are from Jupiter
- 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 Earth's moon, and larger than even the planet Mercury This mammoth moon is the only moon in the solar system with a dense atmosphere, and it’s the
