Jupiter

1. In Roman Mythology, Jupiter was the Supreme Deity. His Greek name was Zeus. See 'Zeus' for more information.

2. Astronomy: Jupiter is the name of the biggest planet of our solar system. It is a gas giant known for its immense size, strong magnetic field, and distinctive bands of clouds that give it a striped appearance. It has a diameter of about 142,984 kilometers (88,846 miles) and is predominantly composed of hydrogen and helium. Jupiter's atmosphere features dynamic weather systems, including the Great Red Spot, a massive storm larger than Earth that has raged for centuries.

The planet has at least 79 moons, with the four largest—Io, Europa, Ganymede, and Callisto—known as the Galilean moons, each with unique characteristics. Jupiter's powerful magnetic field and intense radiation belts make it a fascinating subject of study for scientists seeking to understand the formation and dynamics of our solar system.
