Facts About Jupiter

Jupiter is a world of extremes.

Jupiter is the largest planet in our solar system. If Jupiter was a hollow shell, 1,000 Earths could fit inside. Jupiter also is the oldest planet, forming from the dust and gases left over from the Sun's formation 4.5 billion years ago. But it has the shortest day in the solar system, taking only 10.5 hours to spin around once on its axis.

Exploring Jupiter

The first detailed observations of Jupiter were made by Galileo Galilei in 1610 with a small, homemade telescope.

More recently, this planet has been studied by orbiters, probes, and spacecraft passing by on their way to other worlds. NASA’s Juno spacecraft currently is studying the giant planet from orbit. Europa Clipper will launch in October 2024 to study Jupiter's icy moon, Europa.
