Jupiter — 142,984 km
More massive than every other planet in the Solar System combined — by about two and a half times. Its Great Red Spot, a storm larger than Earth, has been raging for centuries.[1]
Gas giants dwarf the rest — Jupiter's diameter alone is more than eleven times Earth's.

Famous for its rings of ice and rock, Saturn is also the least dense planet in the Solar System — less dense than water, meaning it would float given a large enough bathtub.[1]
Rotates almost completely on its side, with an axial tilt of about 98 degrees — likely the result of an ancient collision. It also has the coldest planetary atmosphere in the Solar System.[1]
The windiest planet in the Solar System, with recorded wind speeds over 2,000 km/h. It takes about 165 Earth years to complete a single orbit of the Sun.[1]
The only terrestrial planet still geologically active with plate tectonics — and, as far as we know, the only planet anywhere with confirmed life.[1]
