Jupiter
Jupiter is the fifth planet from the Sun.Jupiter is the largest planet in the solar
system.Jupiter’s fast rotation causes the clouds
to form bands.Big red spot in southern hemisphere is a
hurricane-like storm.It takes 100 Earths to make 1 Jupiter.

The planet Jupiter's four largest moons are called the Galilean satellites, after Italian astronomer Galileo Galilei, who observed them in 1610.
These large moons are Io, Europa, Ganymede, and Callisto.
Ten of the Moons of Jupiter:
1. Metis
2. Adrastea
3. Amalthea
4. Thebe
5. Io
6. Europa
7. Ganymede
8. Callisto
9. Themisto
10. Leda
The German astronomer Simon Marius claimed to have seen the moons around the same time, but he did not publish his observations and so Galileo is given the credit for their discovery.

Is a ball of hot gases. Is 70% hydrogen, 28% helium, 1.5% carbon,
nitrogen, and oxygen, and 0.5% all other elements.
The Sun's temperature is 10,000 degrees Fahrenheit at the surface and 27,000,000 degrees Fahrenheit at the center.
