Earth's Moon, average384,000 km.(1.3 light sec.)?The Moon'sis 3,476 km.has a mass only 1.25% ofEarth's. Surface gravity onMoon is only .165 ofEarth's. Due to tidal friction with Earth, its rotation rate has become synchronized withEarth so that only one face is visible from Earth. Forsame reason,Earth is gradually slowing downeventually, millions of years from now,length of our day will last a month. The Moon has no atmosphereno water.

Named afterRoman god of speed, Mercury has a year of only 88 days. Its airless surface is covered with craters likeMoon. Once thought to keep one face towardSun, Mercury actually rotates on its axis every 58.6 daysis tidally locked toEarth, notSunVenus, average150 million km.(8.3 light min.)?The 2nd planet outward fromSun was named aftergoddess of lovebeauty. Itsis 12,180 km. (similar to that of Earth)its mass is 82% that of Earth. When far enough away fromSun to be visible, Venus is by farbrightest star-like object insky. Its dense atmosphere is mostly carbon dioxide with no oxygen. Its surface temperature (nearly 500˜ C) is higher thanmelting point of lead. Clouds, probably of sulfuric acid, preventsurface of Venus from being seen; however, radar astronomy has produced maps ofsurface,atmospheric probesunmanned lander spacecraft have begun to uncovermysteries of Venus. The year of Venus lasts 224.7 terrestrial days, while it takes 243 days to turn once on its axis. The time between sunrises on Venus is 118 daysMars, average230 million km.(13 light min.)?The 4th planet fromSun was named afterRoman god of war. Mars has aof 6,760 km.has 11%mass ofEarth. It has a thin atmosphere, mostly carbon dioxide with a small amount of nitrogen. The surface of Mars is heavily cratered,shows evidence of surface erosion by air-born dust. Some features appear to have been formed by flowing water, at some time in its distant past. Its polar caps are frozen carbon dioxide. It has two small moons, named DeimosPhobos ("panic""fear"), afterchildren of Mars. Mars rotates around its axis in 24.6 hourstakes 687 days to complete one orbit aroundSunJupiter, average780 million km.(43 light min.)?The 5th planet fromSun lies outsideasteroid belt. Jupiter islargest planet (142,700 km.)most massive (318x that of Earth) but it is composed mainly of hydrogen, helium, methaneammonia. For this reason it is called a gas giant. Jupiter may have a super compressed core of solid metallic hydrogen. One can regard Jupiter as a star which didn't quite turn on when it condensed out ofnebula which gave rise toSolar System. Jupiter has a large family of moons, 4 of which can be seen with binoculars (Ganymede, Callisto, Io,Europa). Several other Jovian moons can be seen through a telescope. Jupiter takes only 10 hours to rotate once around its axiscompletes one orbit aroundSun in 11.9 yearsSaturn, average1,430 million km.(79 light min.)?In Roman mythology, Saturn wasfather of Jupiter andruler of Time6th planet fromSun has aof 120,900 km.is 95x as massive asEarth. Because oflargebright ring system surrounding it, Saturn is an extraordinary sight through a telescope. Like Jupiter, Saturn is composed mainly of gases. Saturn's moon Titan is2nd largest satellite inSolar System, larger thanplanet Mercury (Jupiter's Ganymede is slightly larger). Titan has an extensive atmosphere containing methane. Saturn has several other satellites, 9 of which can be seen through large telescopes. Saturn rotates around its axis once in about 10 hourscompletes one orbit aroundSun in 29.5 yearsUranus, average2,900 million km.(2.7 light hrs.)?The 7th planet outward fromSun, Uranus has aof 46,700 km.a mass 15x that of Earth. In both RomanGreek mythology, Uranus wasgrandfather of Jupiter (Zeus)waspersonification ofSky. Almost invisible tonaked eye (5.7), Uranus can be seen as a tiny disk through a telescope. Space probes have revealed a faint ring system around it. Uranus, with 5 moons, completes one orbit in 84 yearsNeptune, average4,500 million km.(4.2 light hrs.)?Named afterRoman god ofsea, Neptune is8th planet outward fromSun. It has aof 49,500 km.is 17x as massive asEarth. Too faint to be seen withnaked eye, it was not discovered until 1846, when both Adams (English)Leverrier (French) independently predicted its position. Neptune has 2 known large satellites. Neptune completes one orbit in 165 yearsPluto, average5,900 million km.(5.4 light hrs.)?Pluto, named afterRoman god ofunderworld, is9thlast known planet outward fromSun. Itsis only 2,200 km.it is 380x less massive than Earth. Extremely faint (approx. 15), Pluto is visible only through large telescopes. It was discovered, after an extensive search, on long-exposure photographic plates in 1930. Its year has been calculated to be 248 Earth-years,its orbit is highly eccentric, taking it insideorbit of Neptune for about 20 years. Pluto has a rotation period of 6.39 daysits one satellite, Charon, named afterboatman of Hades, is gravitationally locked to PlutoComet Halley, visible Sept 1985 through Aug 1986.
