This is Ruth's website about Jupiter

Jupiter is the fifth planet from the Sun and by far the largest. 
        
    	orbit:    778,330,000 km (5.20 AU) from Sun 
        diameter: 142,984 km (equatorial)
        mass:     1.900e27 kg

The vivid colors seen in Jupiter's clouds are probably the result of subtle chemical reactions of the trace elements in Jupiter's atmosphere, perhaps involving sulfur whose compounds take on a wide variety of colors, but the details are unknown.

The colors correlate with the cloud's altitude: blue lowest, followed by browns and whites, with reds highest. Sometimes we see the lower layers through holes in the upper ones.

Jupiter is about 90% hydrogen and 10% helium (by numbers of atoms, 75/25% by mass) with traces of methane, water, ammonia and "rock". This is very close to the composition of the primordial Solar Nebula from which the entire solar system was formed. Saturn has a similar composition, but Uranus and Neptune have much less hydrogen and helium.

• Jupiter radiates more energy into space than it receives from the Sun.
• Jupiter is just about as large in diameter as a gas planet can be.
• Jupiter has a huge magnetic field, much stronger than Earth's.
