Jupiter and its moons. *If you’re looking from the southern hemisphere, Jupiter will rise in the northeastern sky. Jupiter will be easy to spot for most of June. It is the innermost of the Galilean satellites of Jupiter, its orbit lying between those of Thebe and Europa. Jupiter has 53 named moons and another 26 awaiting official names. On April 3, 2017, Hubble viewed our solar system’s largest planet in all of its up-close glory — a mere 415 million miles away. They took more than 33,000 pictures of Jupiter and its five major satellites. Photography of Jupiter began in January 1979, when images of the brightly banded planet already exceeded the best taken from Earth. There are many interesting moons orbiting the planet, but the ones of most scientific interest are the first four moons discovered beyond Earth—the Galilean satellites.

Voyager 1 completed its Jupiter encounter in early April, after taking almost 19,000 pictures and many other scientific measurements. Again in 1996, the exploration of these worlds took a large step forward as the Galileo spacecraft began its long term mission of observing Jupiter and its moons. Viewing will be best a few hours after dark falls. Including Jupiter's inner satellites, Io is the fifth moon out from Jupiter. Voyager 1 completed its Jupiter encounter in early April, after taking almost 19,000 pictures and many other scientific measurements. Io orbits Jupiter at a distance of 421,700 km (262,000 mi) from Jupiter's center and 350,000 km (217,000 mi) from its cloudtops. Combined, scientists now think Jupiter has 79 moons. The picture shows Jupiter and its four largest moons.

Most of Jupiter's moons are relatively small and seem to have been more likely captured than to have been formed in orbit around Jupiter. Voyager 2 picked up the baton in late April and its encounter continued into August.

Juno's camera and science instruments were shut off before the Jupiter orbit insertion rocket firing in July 2016. See more ideas about Jupiter moons, Solar system and Astronomy. Voyager 2 picked up the baton in late April and its encounter continued into August.
