In Depth | Moons – NASA Solar System Exploration In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons As these planets grew in the early solar system, they were able to capture smaller objects with their large gravitational fields
In Depth | Enceladus – NASA Solar System Exploration Also, like some other moons in the extensive systems of the giant planets, Enceladus is trapped in what’s called an orbital resonance, which is when two or more moons line up with their parent planet at regular intervals and interact gravitationally Enceladus orbits Saturn twice every time Dione, a larger moon, orbits once
Voyage: A Solar - NASA Solar System Exploration Lesson Overview It is challenging to design a scale model of the Solar System where the same scale is used to portray not only the physical sizes of the Sun and planets, but also the distances between them Planets are tiny worlds in a vast space In October 2001, the Voyage Scale Model Solar System opened in Washington, DC, displaying a one to ten billion scale of the sizes of the Sun and planets, and the distances between them In this lesson, students will replicate the Voyage model to
In Depth | Europa – NASA Solar System Exploration In fact, the Galilean moons are sometimes called a “mini solar system” since they formed from the leftovers of Jupiter similar to how Earth and other planets formed from gas and dust left over from the formation of the Sun The similarities don’t end there
The Sun By the Numbers - NASA Solar System Exploration The Sun is the star at the heart of our solar system Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest bits of debris – in its orbit
In Depth | Titan – NASA Solar System Exploration In Depth 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
