Jupiter and its 4 largest moons will line up in the sky on Aug. 8. Here's how to see the 'parade'

The positions of Jupiter and its four largest moons are shown for the night of August 8. Europa is closest to the gas giant, followed by Io, Ganymede and Callisto.

The predawn hours of Aug. 8 present a perfect opportunity to see Jupiter's four largest moons line up next to the "King of the Planets" as it voyages through the stars of the constellation Gemini.

Stargazers in the U.S. will see Jupiter rise above the eastern horizon roughly two hours before sunrise on Aug. 8, with Venus visible as a bright morning "star" less than 5 degrees to its upper right.
