Most of us know that Jupiter is the largest planet of the solar system. Well, there’s more to Jupiter than the size alone with these other mind-blowing facts!
Jupiter is only behind the Sun, the Moon and Venus in terms of brightness. Needless to say, Jupiter can be seen by the naked eye.
Jupiter has the shortest day as it spins the fastest among all other planets. It turns on its axis once every 9 hours, 55 minutes and 29.69 seconds.
Jupiter is composed of hydrogen and helium, so it has no solid surface.
Jupiter has the most moons, with 67 of them confirmed. The planet’s largest moon is Ganymede, one of the four “Galilean moons” discovered by Galileo Galilei. Check out our separate gallery about the other moons in the solar system.
That spot is commonly called the “Great Red Spot” — a huge, swirling storm that has raged for at least 350 years. The storm is so enormous that about three Earths could fit inside it.
So far there are a total of nine spacecrafts which have done missions on Jupiter: Pioneer 10 and Pioneer 11, Voyager 1 and Voyager 2, Galileo, Cassini, Ulysses, New Horizons and Juno.
Not surprisingly, Jupiter’s magnetosphere is the biggest in the solar system, with its magnetic field being 20 times more powerful compared to Earth’s.
It was the ancient Babylonians who first spotted Jupiter around 7th or 8th BC. They employed advanced mathematical and geometrical skills to help them track its movements across the night sky.
Jupiter’s upper atmosphere is split into zones and cloud belts, which are chiefly composed of ammonia crystals, sulfur, and a combination of the two.
Jupiter doesn’t experience seasonal changes unlike Earth and Mars, because it has very small axial tilt — only 3.13 degrees.
