Jupiter is the largest planet in the Solar System. Its striped atmosphere hosts powerful storms, including the long-lived Great Red Spot.
- Diameter: about 11 times Earth’s
- Day: about 9 h 56 min
- Galilean moons: Io, Europa, Ganymede, Callisto
Use the 3D view to focus on Jupiter and select its represented moons to compare their sizes and orbital fields.

About Jupiter
Jupiter is the largest planet in the Solar System — more than twice as massive as all the other planets combined and about 11 times Earth’s diameter. It is a gas giant made mostly of hydrogen and helium, with no solid surface. Its colourful stripes are cloud bands stretched by fast rotation: a day on Jupiter lasts under 10 hours, the shortest of any planet.
The Great Red Spot is a storm larger than Earth that has been observed for well over 150 years. Jupiter has more than 90 known moons, including the four large Galilean moons discovered in 1610: volcanic Io, ice-covered Europa, Ganymede — the largest moon in the Solar System — and Callisto. NASA’s Juno spacecraft has orbited Jupiter since 2016.
Jupiter: frequently asked questions
Can you stand on Jupiter?
No. Jupiter has no solid surface; its hydrogen and helium atmosphere simply gets denser and hotter with depth.
How big is Jupiter compared with Earth?
Jupiter is about 11 times wider than Earth, and more than 1,300 Earths could fit inside it.
What is the Great Red Spot?
A giant, long-lived storm spinning in Jupiter’s southern hemisphere. It is wider than Earth and has been watched for well over 150 years, although it has been slowly shrinking.
