Europa - liquid ocean may lie beneath its frozen crust. has about 99% the diameter of the planet Mercury but only about a third of its mass. Ganymede - the largest planetary moon and the only moon in the solar system known to 64 confirmed Moons have its own Mass of moons magnetic field.

The Great Red Spot storm that’s larger than Earth. its swirling winds blow 100km/hr similar to a hurricane. hurricanes on earth weaken quickly. Jupiter -> there is no land to weaken the storm. Infrared Image 1st observed in mid-1600’s lasted 181 years and possibly longer than 346 years. visible through Earth-based telescopes.
Interesting Facts about JJupiter has 2.5 times the mass of all the Jupiter got any more massive, itother planets in the Solar System would actually get smaller and dense.combined.Astronomers call Jupiter a failed star. Not really appropriate, it’s like saying your house is a failed skyscraper.Stars generate their energy through Jupiter would need more than 70the fusion of mass together. times its current mass to ignite nuclear fusion. After crashing dozens of Jupiters together, you might have a chance to make a new star.
