The planet Jupiter is famed for its immense size (a radius of 43,440.7 miles or 11 times wider than Earth) and its Giant Red Spot, a storm that has raged on the planet for hundreds of years. The fifth planet from the sun is not only the biggest in our solar system, but it also, according to the International Astronomical Union’s Minor Planet Center (MPC), has the most moons. Astronomers discovered 12 new moons around Jupiter over the past two years, making the total number of Jovian moons 92.
The discovery knocks Saturn and its 83 confirmed moons out of first place. Both Jupiter and Saturn have tons of small moons that are believed to be fragments of bigger moons that have collided with comets, asteroids, and each other.
As for the other planets in our solar system, Mercury and Venus are moonless, Earth has one, Mars has two moons, Uranus has 27 confirmed moons, and Neptune clocks in at 14.
