Mars Has two known satellites Jupiter Jupiter Largest planet in our solar system Rotates faster than any planet in the solar Rotates system (10 hours) system Jupiter is covered with multicolored bands Jupiter of clouds of Has the “Great Red Spot” Red spot is believed to be caused by a Red cyclonic storm cyclonic Jupiter (cont.) Jupiter Atmosphere Atmosphere consists mainly of hydrogen and helium and Surface pressure is great enough to Surface compress hydrogen gas into a liquid compress Jupiter (cont.) Jupiter Atmosphere Atmosphere consists of hydrogen and helium helium Has 63 known satellites. The four largest moons were discovered The by Galileo by Galilean Moons Galilean Jupiter’s Jupiter’s four largest moons: a) Io b) Europa c) Ganymede d) Callisto Europa All of these moons are very cold, have no All atmosphere atmosphere Galilean Moons (cont.) Galilean Io is most volcanically active Europa is the smallest of the Galilean Europa moons. Ganymede is the largest moon. Contains Ganymede cratered areas, smooth regions and areas covered by grooves covered Callisto is very heavily cratered Saturn Saturn Atmosphere Atmosphere is similar to Jupiter (hydrogen and helium) and Saturn is known for its rings Has a very dynamic atmosphere (winds Has topping about 930 mph) topping Rings consists mostly of dust, rock, and Rings ice. ice. Average surface temperature: -180oC. Saturn (cont.) Saturn Saturn Saturn requires almost 30 years to make one revolution around the sun one Rings were first observed by Galileo in Rings 1610 1610 Atmosphere is primarily hydrogen (75%) Atmosphere and helium (25%) and Uranus & Neptune Uranus Considered to be twins Both planets are bluish in appearance Uranus is the smaller of the two planets Atmospheres are very similar (consists of Atmospheres hydrogen, methane, and ammonia hydrogen, Uranus’s atmosphere is quiet Neptune’s atmosphere is dynamic Uranus tends to rotate on its side Uranus has rings Uranus revolution period about the sun is Uranus 84 years 84 Neptune’s revolution about the sun is 165 Neptune’s years years Uranus & Neptune (cont.) Uranus Uranus has 27 known satellites Neptune has 13 known satellites Neptune’s largest moon is Triton Triton Triton Triton’s Triton’s volcanoes erupt ices (rather than rocks) rocks) Triton’s magma consists of a mixture of Triton’s water-ice, methane and ammonia water-ice, Pluto Pluto Very far from the sun Very cold (-340oF) Period of revolution: 248 years Has one known satellite, called Charon.
