Jupiter

Jupiter is the planetary Goliath in our solar system. More than 1,300 Earths can fit inside this gas giant, and it may actually shield our world from collisions with comets. Scientists theorize that Europa, one of Jupiter’s moons, is our best bet for finding extraterrestrial life.

Dive in to learn more about Jupiter, its moons, and the Juno mission.
