The discovery, along with three other Jovian moons, was the first time a moon was discovered orbiting a planet other than Earth. As the nebula collapsed because of its overwhelming gravity, it spun faster and flattened into a disk. There may be dozens of dwarf planets in our solar system. Stormy Jupiter is swept by over a dozen prevailing winds, some reaching up to 335 miles per hour (539 kilometers per hour) at the equator. The temperature drops below 3.5 million degrees Fahrenheit (2 million degrees Celsius) in the convective zone, where large bubbles of hot plasma (a soup of ionized atoms) move upwards. This unit provides an easy way to quickly compare planets' distances from the sun. The sun's magnetic field is carried out through the solar system by the solar wind — a stream of electrically charged gas blowing outward from the sun in all directions. The extreme pressures and temperatures would destroy a metal spacecraft. These historic comet annals have proven to be a valuable resource for later astronomers.

Scientists have long wanted to study comets in some detail, tantalized by the few 1986 images of comet Halley's nucleus. These historic comet annals have proven to be a valuable resource for later astronomers. Hungrier observers compared its craters to cheese and dreamed of an entire sphere made of delicious dairy products. The particles and gas escape the surface at jet speed at approximately 800 miles per hour (400 meters per second). The measurements suggested a large sea about 6 miles (10 kilometers) deep beneath the southern polar region, under an ice shell about 19 to 25 miles (30 to 40 kilometers) thick. The dunes are not unlike those seen in the desert of Namibia in Africa. Short-period comets evaporate so quickly compared to the age of the solar system that we shouldn't see any, yet astronomers routinely track dozens of them. Some of the giant shield volcanoes are younger, having formed between 1 and 2 billion years ago. Ceres is covered in countless small, young craters, but none are larger than 175 miles (280 kilometers) in diameter.
