Jupiter is surrounded by a faint system of planetary rings and has a powerful magnetosphere, the second-largest contiguous structure in the Solar System (after the heliosphere). Jupiter forms a system of 95 known moons and probably many more, including the four large moons discovered by Galileo Galilei in 1610: Io, Europa, Ganymede, and Callisto.
The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
Apparent planetary alignment involving Mercury, Venus, Mars, and Jupiter; the Moon is also shown, as the brightest object. Because the orbits of all the planets in the Solar System (as well as the Moon) are inclined by only a few degrees, they always appear very near the ecliptic in our sky.

Mars and Jupiter are cozying up in the night sky for their closest rendezvous this decade. In reality, our solar system’s biggest planet and its dimmer, reddish neighbor will be more than 350 ...
The closest in the past 1,000 years was in 1761, when Mars and Jupiter appeared to the naked eye as a single bright object, according to Giorgini. Looking ahead, the year 2348 will be almost as close.
Juno is also searching for clues about how Jupiter formed, including whether the planet has a rocky core, the amount of water present within the deep atmosphere, and how the mass is distributed within the planet. Juno also studies Jupiter's deep winds, [58] [59] which can reach speeds of 600 km/h. [60] [61]
