Jupiter is the largest planet in our solar system and the fifth from the sun. The gas giant is 2.5 times the mass of all the other planets circling our sun. The planet was named for the Roman god Jupiter, who ruled over laws and social order. In December, Jupiter and Venus will be the brightest objects in the night sky other than the moon.
Thanks to several missions by NASA — including the Voyager and Cassini flybys, the Galileo orbiter and the Hubble telescope — we're able to understand our biggest planetary neighbor as never before. (Text: Katherine Butler)
