What does Jupiter look like?
Jupiter has swirling clouds of white, brown, red, and yellow gas. It almost looks like it has stripes.
The temperature in Jupiter’s clouds is about –234 degrees Fahrenheit (–148 degrees Celsius). Its core is believed to be even hotter than the sun, however!

What is it like on the surface of Jupiter?
Jupiter is a gas giant. It has an atmosphere of hydrogen and helium surrounding the planet. You would not be able to breathe
on Jupiter!
You probably wouldn’t be able to stand on Jupiter, either. Scientists believe Jupiter does not have a solid surface like Earth does. If you went to Jupiter, you would sink through its clouds. As you get closer to Jupiter’s core, the clouds get denser, or more pressed together.

the solar system. It is even bigger than the planet Mercury.
There is a storm on the surface of Jupiter called the Great Red Spot. The Great Red Spot is bigger than the planet Earth! The storm has existed for more than 400 years.
