B is wrong.  Jupiter spins once every 9 hours and 55 minutes while earth spins once every 24.

Mars is the name of a Greek god, the god of war. Mars has been named after war gods in almost all society's that observed it. \n\nLook up Robert Zubrin, he is an amazing scientist! His book "The Case for Mars" covers his great method for making fuel out of the martian atmosphere. It also contains loads of info on past space missions. Yahoo him or the Mars Society and get some info!

Yes. he is another form of marsian. i dont understand why is NASA launching vehicles to mars in serach of life, bush is the represntaive of mars, research on him.

Damn! Left out again! Not a C or an A. Why do these 2 groups fight all the time? It is getting boring. Old. Sick of it.\nLove & Light\nSharon\nOne Planet = One People

You are confusing the terms here.\n\nOnly planets outside the orbit of the Earth (superior) are ever at opposition.  Opposition is when the Sun, Earth and that planet line up in that order*.  Therefore, Mars, Jupiter, Saturn, Uranus and Neptune can all be at opposition.  Inferior planets though that orbit inside the Earth's orbit, (namely Venus and Mercury) can never be at opposition because their orbits will never take them past the Earth so that the Earth will be between them and the sun.\n\nInferior planets can, however be at conjunction.  This is when either the planet, sun and Earth line up in that order or the sun, the planet and the Earth line up in that order*.\n\nOpposition is an alright time to view a planet because it is fully illuminated.  If a light source is behind you and you look at something you see it is totally illuminated (assuming it's far enough away for your shadow to not interfere).  The conjunction that Mercury and Venus expirience is a very bad time to view the planets because either they are infront of the sun from our point of view and so we can't make the planet out in the blinding light, or it is behind the sun from our point of view anyway*.

There's really only one 'icy planet', and that's Pluto.  Mercury, Venus, Earth, and Mars are all terrestrial planets, while Jupiter, Saturn, Uranus, and Neptune are all jovian.  That leaves Pluto, and maybe that new one if they decide to call it a planet.

Jupiter has more mass than all other planets combined.\n\nIt does not have more moons (that we know of) than the others combined.  Jupiter has 62 known moons, the rest have 77 together.\nhttp://www.spacetoday.org/SolSys/Moons/MoonsSolSys.html\n\nIt also does not have greater surface gravity than the others combined.  It does have the greatest surface gravity due to it's huge mass, but since it also has a huge radius, it's surface gravity is only 2.6 times that of earth, and less than half that of all other planets combined.\nhttp://erc.arc.nasa.gov/HowBig/gravity.htm

Mars is a bright, red object in the sky. It is very easy to see, which means that even people that lived long ago knew it was there. So, we don't know who discovered it. We do know it was named after the Roman god of war. \n\nA scientist named Giovanni Schiaparelli saw many long lines on Mars. He thought they were water canals made by creatures! Later we sent spacecraft to Mars to study it. \n\nMariner 9 was the first to orbit Mars. It took lots of pictures of volcanoes and craters. It even found Olympus Mons, a giant volcano! The Viking I and II spacecrafts landed on Mars and studied rocks and the soil. Even today the Mars Global Surveyor is mapping the planet!

In 1968 Ragni and Rado's hippy musical Hair featured the following lyrics:\n\n"When the Moon is in the Seventh House\nAnd Jupiter aligns with Mars\nThen peace will guide the planets\nAnd love will steer the stars\n\nThis is the dawning of the Age of Aquarius\nThe Age of Aquarius\nAquarius!\nAquarius!"\n\nAs is implied by these lyrics, Jupiter and Mars aren't always aligned. They move into alignment and out of it again, Their years are of different lengths (Mars 1.88 Earth years and Jupiter 11.86 Earth years)\n\nFor a simple picture (ignoring the fact the orbits are ellipses), the radius of Jupiter's orbit is 5 AU and the radius of Mars' orbit is 1,5 AU.\n\nTheir mutual separation can vary widely e.g. when they are both on the same side of the sun, ir can be as little as 3.5 AU, when they are 180 degrees away from one another in their orbits, with the Sun inbetween them, it is more like 6.5 AU.\n\nBut the fact that the orbits are not circular but elliptical will make it more complicated as the question of whether the planets are at aphelion (the furthest they get from the Sun) or at perihelion (the nearest they get to the Sun) becomes highly relevant.\n\nIf Mars is at aphelion when Jupiter is at perihelion that will produce the minimum Mars-Jupiter seoparation at alignment and conversely if Mars were to be at perihelion and Jupiter at aphelion, that will produce the maximum Mars-Jupiter separation at alignment,\n\nHere are the figures;\n\nJupiter: Perihelion: 4.951 AU. Aphelion: 5.455 AU.\nMars: Perihelion: 1.381 AU. Aphelion: 1.665 AU\n\nWhich gives us a minimum  Mars-Jupiter distance at alignment of 4.951 - 1,665 AU = 3.286 AU.\n\nAnd gives us a maximum  Mars-Jupiter distance at alignment of 5.455 - 1,381 AU = 4.074 AU.\n\nWhen they are 180 degrees away from one another with the Sun directly between them ... it is a matter of adding the perihelion distances for the closest they can be and adding the aphelion distances for the furthest they can get from one another.\n\nWhich gives us a minimum  Mars-Jupiter distance when 180 degrees apart of 4.951 + 1,381 AU = 6.332 AU.\n\nAnd gives us a maximum  Mars-Jupiter distance when 180 degrees apart of 5.455 + 1,665 AU  = 7.120 AU.

Venus, Mars, Mercury, Pluto and that new one are big rocks just like Earth, whereas Jupiter, Saturn, Uranus and Neptune are balls of gas.\n\nMars and Venus are the most comparable in mass (with Venus very close and often called our sister planet).  Mars has polar ice caps.

Scientists using NASA's Spitzer Space Telescope have discovered and directly imaged a small brown dwarf star, 50 times the mass of Jupiter, orbiting with a planet around a Sun-like star. Such an arrangement has never before been seen but might be common, the scientists say, leading to solar systems with distorted planetary orbits.\n\nKevin Luhman of Penn State University is the lead author on a report describing this discovery, which will be published in The Astrophysical Journal. The discovery concerns a class of the coldest brown dwarfs, called T dwarfs.\n\n\nThe detailed research paper on T dwarf - Ref\nhttp://www.science.psu.edu/alert/Luhman9-2006-2.htm

Jupiter is definitely a planet, a gas giant type. Sometimes the Jovian system - the huge planet with its moons, taking their number and size of the largest ones, is referred to "LIKE a mini solar system". Jupiter is not a star though, and it is not a brown dwarf. Though Jupiter has a major gas atmosphere it still has a metallic core. A browm dwarf, an intermidiary between a star and planet, is totally made of gas, so there is a full convection between its outer and inner layers, unlike Jupiter.

Actaully, our liuck with finding planets is no good.  No planets have liquid water, and all of them are gas giants like jupitur.  They are also to hot to support almost any life (1300f is so-so temperature!).\n\nPlanets that can actually support us will be nearly impossible to find.  Had you asked this question 3 months ago, I could show you some neat sources about it.  \n\nI don't beleive Bush is doing Atrocious, but I do think he has made some poor decisions.\n\nHowever, I would like to say armegeddion is a christian end of the world.  We are nowhere near that.  WHy?  Ever hear of Ragnarok?  Yep, thats right.  Planets are studied for scientific reasons.  The sun will expand into a red giant and kill earth in 4.5 billion years.\n\nOh, those of you who disagree with me, Like the seeking supporter, show your reasons why you beleive he/she has alot better reasons.  Flash poor reasons, watch how badly I flame your ***!

There are 9 bodies in our solar system officially recognized as "planets" by the International Astronomical Union (IAU).\n\nThere are a number of large bodies, such as asteroid Ceres (between Mars and Jupiter), and Sedna (way out beyond the Kuiper Belt) that are considered candidates, but are unlikely to ever be recognized as planets.  Pluto is sometimes considered too small to be called a planet, but just for historical reasons, the IAU is unlikely ever to "downgrade" it.  \n\nIn 2003 a large body was discovered outside the orbit of Neptune, currently called UB313, and appears to be larger than Pluto.  The IAU is reviewing the definition of "planet" and is scheduled to make a decision in September of this year (2006) as to whether UB313 is officially the 10th planet.  Hopefully then they will give it a cool Greek name. :-)

have you not seen war of the worlds?where did the aliens come from? MARS!!!

Other than the fact that venus is a goddess and mars is a god, I think the main reason was a marketing decision. The book which coined the expression was originally titled:\n\n"The Women are from Venus, the Men are from Uranus"\n\nBut then again, they thought it might be subject to some juvenile pranks. So they switched to Mars. Which is closer to earth, but not as close to the point as Uranus.
