Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter's stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.
Jupiter is a gas giant and so lacks an Earth-like surface. If it has a solid inner core at all, it’s likely only about the size of Earth.

Jupiter is the fifth planet from the Sun, and the largest in the solar system – more than twice as massive as the other planets combined.
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
Europa orbits Jupiter every 3.5 days and is locked by gravity to Jupiter, so the same hemisphere of the moon always faces the planet. Jupiter takes about 4,333 Earth days (or about 12 Earth years) to orbit the Sun (a Jovian year).
Jupiter's menagerie of moons includes the largest in the solar system (Ganymede), an ocean moon (Europa) and a volcanic moon (Io). Many of Jupiter's outer moons have highly elliptical orbits and orbit backwards (opposite to the spin of the planet).
The Kuiper Belt is one of the largest structures in our solar system – others being the Oort Cloud, the heliosphere, and the magnetosphere of Jupiter. Its overall shape is like a puffed-up disk or donut.
way to Saturn started observations of the planet Jupiter. The first data from the Ultraviolet Imaging Spectrograph (UVIS) clearly show the planet's aurora and a glowing ring of gas ejected from Jupiter's moon Io. This donut of atoms is known as the Io torus. Our pictures are the first published imaging spectroscopy
Juno, the second mission in NASA's New Frontiers Program†, launched flawlessly on Friday, August 5th, on a journey to Jupiter. It will be the first spacecraft to orbit Jupiter from pole to pole and peer far underneath the clouds. That cloud layer cloaks endless mysteries. It's amazing how much we don't know about our largest planet!
