Jupiter The largest planet in the solar system. Stripes and swirls are cold, windy clouds of ammonia and water. Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years. Surrounded by 53 confirmed moons, as well as 14 provisional ones. Has three rings, but they are very hard to see. Eleven times wider than Earth. If Earth were the size of a nickel, it would be about as big as a basketball. Has the shortest day in the solar system…only about 10 hours. Makes a complete orbit around the sun in about 12 Earth years. Spins nearly upright and does not have seasons as extreme as other planets do. Has the same ingredients as a star, but it did not grow massive enough to ignite. The fifth planet from the sun. The composition is similar to that of the sun — mostly hydrogen and helium. Took most of the mass left over after the formation of the sun, ending up with more than twice the combined material of the other bodies in the solar system. Home to the largest ocean in the solar system — an ocean made of liquid hydrogen instead of water. As a gas giant, there is no true surface. The gas planet likely has three distinct cloud layers in its "skies” Saturn The most distant of the five planets known to the ancients. Winds in the upper atmosphere reach 500 meters per second (1100+ mph) Rings are made mostly of water ice, and can contain "braided" rings, ringlets, and "spokes" Ring system extends thousands of miles from the planet, yet the vertical height is typically about 30 feet in the main rings. Fifty-three confirmed moons and another 9 provisional moons. Has many smaller "icy" satellites. Italian-born astronomer Cassini discovered a "division" between what are now called the A and B rings of the ring system. The gravitational influence of the moon Mimas is responsible for the Cassini Division, a 3000 mile wide gap in the ring system. Second largest planet in the solar system. Sixth planet from the Sun. Super-fast winds, combined with heat rising from within the planet's interior, cause the yellow and gold bands visible in the atmosphere. Aurorae occur when charged particles spiral into a planet's atmosphere along magnetic field lines.
