Jupiter is the biggest planet in our solar system and you can sometimes see it at night. Right now you would have to get up at about 3:30 and look in the south east sky to see Jupiter.
This information came from Compton's Encyclopedia. There are also good books in your school library about the Solar System.
Jupiter is composed mostly of hydrogen and helium. It has no solid surface, only layers of gaseous clouds. At the planet's center is probably a rocky core with more than ten times the mass of the planet Earth. Temperatures in the core may exceed 25,000 K. Surrounding the core is a liquid hydrogen-helium mixture that has been squeezed into metallic form under the intense pressure of the planet's upper layers.
So, if you were to travel into Jupiter, you would drop down into clouds. You would keep dropping until it became very dark, hot and the pressure of the atmosphere was crushing. Not a nice place to visit!
