What is Jupiter's surface like?

Instead of having a rocky surface, Jupiter is gaseous up to the inner core, which is either rock or a molten liquid. The gases in its atmosphere include hydrogen and helium.

There are no visible landmasses on Jupiter, and its surface gravity is 2 1/2 times stronger than that of Earth. Colorful clouds of red, brown, yellow and white paint the surface of Jupiter. This includes the Great Red Spot, which is actually a hurricane that has brewed for at least 300 years. The rest of Jupiter experiences high volumes of wind up to 400 miles per hour, and the average temperature is about -234 degrees Fahrenheit.
