Orbit
Jupiter travels once around the Sun every 12 years and spins on its own axis every 10 hours compared to 24 on Earth, making it the fastest spinning planet in the Solar System.
Atmosphere
The atmosphere of Jupiter is composed of about 86 percent hydrogen, 14 percent helium, and tiny amounts of methane, ammonia, phosphine, water, acetylene, ethane, germanium, and carbon monoxide.
Temperature
The temperature at the top of Jupiter's clouds is about -145C (-230F). Deeper below the clouds the temperate reaches 21C (70F). Near the planet's centre the temperature is hotter than the surface of the Sun!
