Jupiter rotates once about every 10 hours (a Jovian day), but takes about 12 Earth years to complete one orbit of the Sun (a Jovian year).

Jupiter: What's Inside

Post by Joseph Buell » Fri Jan 15, 2021 2:01 am

Jupiter is a gas giant and so lacks an Earth-like surface. If it has a solid inner core at all, it’s likely only about the size of Earth.

Jupiter cannot support life as we know it. But some of Jupiter's moons have oceans beneath their crusts that might support life.

In the process of tidal heating, the gravitational pull of Jupiter's satellites and the planet itself stretches and squeezes the satellites enough to warm them. As a result, some of the icy moons are warm enough to house oceans of liquid water, and in the case of the rocky moon Io, tidal heating turns the rock into magma.
