Io orbits the planet Jupiter, which itself orbits the Sun at a distance of 484 million miles (778 million kilometers).

2024年5月16日 · The speed needed for an object to break away from the gravitational pull of a planet or moon.

1995年11月9日 · 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 …

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 …

Jupiter’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.

2025年1月9日 · 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.

2003年2月26日 · Using a sensitive new imaging instrument on NASA's Cassini spacecraft, researchers have discovered a large and surprisingly dense gas cloud, called sharing an orbit …

One day on Jupiter takes only about 10 hours (the time it takes for Jupiter to rotate or spin around once), and Jupiter makes a complete orbit around the Sun (a year in Jovian time) in about 12 …

The Moon makes a complete orbit around Earth in 27 Earth days and rotates or spins at that same rate, or in that same amount of time. Because Earth is moving as well – rotating on its …

2008年10月9日 · Enceladus orbits Saturn twice every time Dione, a larger moon, orbits once. Dione’s gravity stretches Enceladus’ orbit into an elliptical shape, so Enceladus is sometimes …
