The planet Jupiter is named after the Roman God, Jupiter, God of the sky. Jupiter is the largest planet in the solar system and is the fifth planet from the sun.
Because Jupiter is mostly made up of gas (hydrogen and helium) it has no surface. However, it is believed that at the core of Jupiter is dense and made up of different elements. The core is sometimes referred to as rocky, but its exact composition is unknown.
Jupiter may be best known for the Great Red Dot, a constant anticyclonic storm that occurs on Jupiter. The storm has been occurring for more than 186 years. The Great Red Dot is about the same size as Earth.
