King of the planets
Jupiter is the fifth planet from the Sun and the largest in our solar system, with a mass more than twice that of all other planets combined. It is a gas giant with no solid surface, composed primarily of hydrogen and helium. Jupiter's Great Red Spot is a storm larger than Earth that has raged for over 350 years. The planet has a powerful magnetic field and at least 95 known moons, including the four large Galilean moons: Io (the most volcanically active body in the solar system), Europa (which may harbor a subsurface ocean), Ganymede (the largest moon in the solar system), and Callisto.

Instant crush from atmospheric pressure
Gravity of 24.79 m/s² (2.5x Earth) would crush you. There is no solid surface to stand on. No breathable oxygen. Extreme cold of -110°C would freeze you instantly.
Jupiter's Great Red Spot could fit 2-3 Earths inside it
Jupiter has the shortest day of any planet (9h 55m)
Its magnetic field is 20,000x stronger than Earth's
Europa's subsurface ocean may contain more water than all of Earth's oceans
