Jupiter is the giant of the solar system. Its mass is over two times that of all the other planets, moons, asteroids and comets put together.
All the inner planets (Mercury, Venus, Earth and Mars) are largely made of rock. Jupiter is the first of the gas giants.

Jupiter's Moon, Io
Jupiter's moon Io is 778 million kilometers from the Sun. Except at its volcanic hot spots, Io's surface temperature is well below freezing. Instruments aboard the space probe Galileo measured infrared energy emitted by volcanic hot spots on the satellite's surface.

Jupiter-type Comets
Jupiter-type comets are short-period comets with orbital periods less than 20 years. They are named as such since their current orbits are primarily determined by the gravitational influence of Jupiter.

The fifth planet from the Sun and the largest planet in our solar system. Jupiter orbits the Sun at an average distance of 5.2 time Earth's distance (about 465 million miles/745 million km). The planet has a mass 318 times the mass of Earth and a radius 11.2 times the radius of Earth.

Jupiter is the fifth planet from the Sun and by far the largest within our solar system; some have described the solar system as consisting of the Sun, Jupiter, and assorted debris. It and the other gas giants Saturn, Uranus, and Neptune are sometimes referred to as "Jovian planets.

Jupiter's Ring System
Jupiter's ring was discovered by Voyager 1 in a single image that was targeted specifically to search for a faint ring system. Subsequently, Voyager 2 was reprogrammed to take a more complete set of images. The ring is now known to be composed of three major components.

Jupiter, the largest planet
Jupiter is the fifth planet from the sun and the largest in the solar system. Named after the ruler of the gods in Roman mythology, Jupiter has 1400 times the volume of Earth but only 318 times more mass.

Jupiter is the largest planet in our solar system. Not just by a tiny bit, but it is 2.5 times more massive than all of the other planets combined or 317 times the mass of Earth. Sort of an SUV in a solar system full of clown cars.

Jupiter has faint, dark, narrow rings composed of tiny rock fragments and dust. They do not contain ice, like Saturn's rings.

The Great Red Spot is a vast, planet-sized hurricane that's been blowing on Jupiter for hundreds of years. In 2006 it was joined by a smaller storm - though still thousands of miles across - called Oval BA (no relation).

Jupiter XIII
Leda ("LEE duh") is the ninth of Jupiter's known satellites and the smallest: orbit: 11,094,000 km from Jupiter diameter: 16 km mass: 5.68e15 kg Leda was queen of Sparta and the mother, by Zeus in the form of a swan, of Pollux and Helen of Troy.
Discovered by Kowal in 1974.

Jupiter's Europa Harbors Possible "Warm Ice" or Liquid Water
Tantalizing new images of Jupiter's moon Europa from NASA's Galileo spacecraft indicate that "warm ice" or even liquid water may have existed, and perhaps still exists today beneath Europa's cracked icy crust.

A liquid-giant planet whose atmosphere is composed of hydrogen and helium, with methane, ammonia, H2S, and water as condensable aerosols. These gases interact in complex ways to produce rotating horizontal bands and spinning cyclones (such as the Great Red Spot).

Jupiter radiates more energy into space than it receives from the Sun. Traditionally, this heat was thought to be produced from the slow gravitational compression of the planet so that its core may be as hot as 20,000 C (or F).

Jupiter has several unique characteristics:
The first one is its immense size. It is indeed, as its name suggests, the king of the planets. About 1,320 Earths could fit inside of it.
The second characteristic is the Great Red Spot.

Jupiter is composed mostly of gas. This enormous planet radiates twice as much heat as it absorbs from the Sun. It also has an extremely strong magnetic field. It is slightly flattened at its poles and it bulges out a bit at the equator.
Jupiter's diameter is 88,700 miles (142,800 km).

Jupiter is usually one of the brighter objects in the night sky. Amongst the planets visible to the naked eye, it is usually second only to Venus in terms of brightness. With even a modest sized telescope you can see all sorts of details of Jupiter, including cloud features and its major moons.

Jupiter's moons are at it again.
Last week, on August 26-27, you had a chance to see a double shadow on the face of Jupiter, cast by Ganymede and Europa. I had the good fortune to see this event, and it was a splendid sight (though I'm still paying for the sleep deprivation.

Jupiter also has a giant magnetic field--with an equivalent central magnet about 20,000 times the Earth's, its field at the planet's visible edge about 10 times more intense than ours.

Jupiter & Cancer take Center Stage in April
Yearly on April Fool's Day, the constellation Cancer stands due south at 8 p.m. local time, reaching its highest point in the sky for the night. The Sun passes within its borders from July 21 to August 11.

Jupiter is massive because it has a large diameter (11.2 times that of Earth). Its density is only 1.33 g/cc, which is 1/4 that of Earth, and only slightly more than the 1 g/cc characteristic of water.
