- Jupiter
the Galileo spacecraft indicate that Jupiter’s ring system may be formed by dust kicked up as interplanetary meteoroids smash into the giant planet’s four small inner moons. The main ring probably is composed of material from the moon Metis. Jupiter’s rings are only visible when backlit by the Sun.
The table below lists the moons of Jupiter in increasing order of distance from Jupiter. The table also lists the name of each moon, the year it was discovered, its distance from Jupiter, its orbital period, and its radius.
Jupiter has 50 known moons (plus 17 awaiting oficial confirma-tion), including the largest moon in the solar system, Ganymede. Many of Jupiter’s outer moons have highly elliptical orbits and orbit “backwards” (opposite to the spin of the planet).
24 Αυγ 2015 · Galileo's highest-resolution images of Jupiter's ringmoons From left to right, the moons are Metis, Adrastea, Amalthea, and Thebe. All of the images except Adrastea were taken January 4, 2000; Adrastea was taken on December 19, 1996.
The best planets to be observed are Venus, Mars, Jupiter and Saturn because they are big enough to capture some details. Each of them has its own features. Venus has phases, Mars has poles, Jupiter has storms and four big moons and Saturn has rings to put one example of each one.
Mercury, Venus, Mars, Jupiter, and Saturn — and these are the names astronomers use today. Planetary features are named by the International Astronomical Union, founded in 1919.
