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.
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!
The Europa Jupiter System Mission (EJSM) is guided by the overarching theme: the emergence of habitable worlds around gas giants, with goals to determine whether the Jupiter System harbors habitable worlds, and to characterize the processes within the Jupiter system.
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
The fast approaching collision of segmented Periodic Comet Shoemaker-Levy 9 with the planet Jupiter has peaked the interest of professional and amateur astronomers worldwide. Scientists expect a spectacular 51/2-day event from July 16-22 and anticipate some observations.
Io orbits the planet Jupiter, which itself orbits the Sun at a distance of 484 million miles (778 million kilometers).
Data collected by NASA’s Juno mission to Jupiter indicate that the atmospheric winds of the gas-giant planet run deep into its atmosphere and last longer than similar atmospheric processes found here on Earth. The findings will improve understanding of Jupiter’s interior structure, core mass and, eventually, its origin.
