Document Summary

Name the planet jupiter is named after the king of the gods in roman mythology. Size 2 jupiter is the largest planet in the solar system, measuring 88,850 miles in diameter. Location jupiter is the fifth planet from the sun, with an average distance of approximately 484 million miles. Number of satellites 67 known moons. Composition jupiter"s atmosphere is primarily composed of hydrogen (88-92%) and helium (8-12%). Trace constituents jupiter"s atmosphere also contains trace amounts of methane, ammonia, hydrogen deuteride, ethane, water, carbon, hydrogen sulfide, neon, oxygen, phosphine, sulfur, and silicon-based compounds. Traces of hydrocarbons (hydrogen-carbon compounds), such as acetylene and benzene have also been found. The sun"s ultraviolet radiation breaks down the methane in. This process, known as photochemistry, is also responsible for the formation of the earth"s ozone layer, the sulfuric acid clouds of venus, and the trace constituents within the atmospheres of saturn, uranus, and neptune.
