Why is the 10th planet called Sedna, after an Inuit goddess...why pick that name?

1.  We've pretty well exhausted the major Roman gods.  \n \n2.  Sedna is the Inuit goddess of the sea and makes her home in the dark, cold depths of the sea.  This is a pretty good metaphor for the dark, cold depths of space.  There isn't a similar name from the Greek/Roman tradition. \n \n3.  The only source of similar names might be Norse traditions.  The Norse are dead.  The Inuit are not.\n \n4.  Sedna was discovered at an observatory in San Diego, California.  Californians are noted for trying to be inclusive of other people's tradition, what is commonly derisively referred to as being "politically correct."  The International Astronomical Union accepted the name; I don't know where that body's political persuasion tends to lie.

Currently, we have discovered 10 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and Sedna), but there are smaller planets called transneptunian objects that are very small and cannot be detected by current technology. Carla is probably a transneptunian object.

It is the red planet because it is red.  I don't know if the planets were given the names first or the Gods, but either way Mars was the God of war, which I am sure is why that God is associated with that planet.

I'm guessing you mean Sedna.  It is not classified as a planet.\n\nHere's a page on it: http://en.wikipedia.org/wiki/90377_Sedna

NINE, I think senda is not the 10th planet (because of its small size). Nine planets are:\n\nMercury(Roman god of thieves)\nVenus(God of beauty)\nEarth\nMars(God of War)\nJupiter(Supreme Roman god)\nSaturn(God of agriculture)\nUranus(Ruler of the heavens, father of the Titans\nNeptune(God of the sea)\nPluto.

When I was in school, there was 9.  \n\nMercury\nVenus\nEarth\nMars\nJupiter\nSaturn\nUranus \nNeptune\nPluto\n\nNow, there has been another "planet" found.  I am not sure if they have classified it as a planet in our solar system just yet.

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.

It's smaller then Pluto, so I would say no.  There's quite a bit of debate right now as to whether or not Pluto even counts as a planet, but the International Astronomical Union (IAU) has, for now at least, kept Pluto as a planet.  Anything smaller then Pluto (like Sedna) would not be considered a planet.  Of course, that leaves the status of that other new object, UB313, up for grabs.

yeah i think they might be because what are the chance that we are the ONLY ones , and the real name for Xena is A20031 i think . but their still not sure if Pluto a planet now but that's for scientist to discover. It's only a matter of time before we go out to another arm of the milky way and find the one planet in that solar system ( were not the only solar system ya know ) that has life.

why don't u ask this question to our planet?it must give u the right answer,i asked it and it said its name was earth but u should ask it once more,in case it has changed its name from earth to something else..................like sun.

Your question lacks clarity.  Is the question about an element on the periodic table? If it is - and once again, you don't specify - then a likely answer is "Thorium" named after Thor, the greek god of thunder.  I don't know, you didn't actually give any context with the question.  I suggest going to www.wikipedia.com for help with anything, though.   \n\nThe second question, about the order of the planets by rotation - do you have a science book?  That would help you more than the internet because the answers will all be there.  Open the book, go to the chapter(s) about planets, take out a piece of paper, and write down the name of the planet next to the length of the respective planet's day.  When you have all of the written down, you will be able to order it.  \n\nHere is some extra help for you for a question you did not ask but clearly need answered:\n\n"Your" is possessive - "Your eyes are like deep buckets of molasses" \n\n"You're" is an abbreviation of "You are".

Yes, and the people who found it honestly want to have it called Xena.\n\nOn July 29, 2005, a Trans-Neptunian object called 2003 UB313 was announced, which on the basis of its magnitude and simple albedo considerations is assumed to be larger than Pluto. This caused its discoverers to call it the "10th planet" of the solar system, although there is no consensus yet on whether to call it a planet, and others consider the new discovery to be the strongest argument yet for demoting Pluto to the status of a minor planet.\n\nBut until then, it's being refered to as Planet X.

2003 UB313 is the name of the object.  "Xena" is the name given to it by the discoverer's team as a code-word.  Even Mike Brown (the guy who found it) says that it should not seriously be considered the name for it.  Brown is also the guy who helped find Sedna, an object a bit smaller than Pluto (2003 UB313 is actually larger than Pluto).\n\nNo planets have officially been added, or taken away, so neither 2003 UB313, nor Sedna are officially planets.  The problem is that there are a heck of a lot of objects the size of Sedna.  We are currently in meetings off and on discussing this "planet or not" issue.\n\nAs far as how long has it been there, we feel that it was formed at the same time all the other largish solid bodies in the solar system were formed, about 4.5 billion years ago.  It is red in color, made of ice, and if it were brought near the sun it would look like a really big comet.  It has always been there, it is just that only really in the last 10-15 years have we had the ability and instruments to really search for small worlds this far away from us.  The discovery of Pluto in 1930 involved a lot of luck.

Often many people get involved in discovering a "planet" as several observations are required to verify and calculate the orbit.  Exactly what a planet is is subject to debate as even Pluto is not completely accepted as one.  The debate includes the question "how big does a rock have to be for us to call it a planet as opposed to an asteroid?"  Planet X was one possibility that seemed to just fade out of the news.  "Buffy" is the nickname of the latest "unusual" object out there (see my source article).  Heheheh, yes, "Xena" came public a few days before "Buffy."  Both are among the many rocks in the Kuiper Belt, including Pluto.  NASA's launching a probe called "New Horizons" to check out Pluto and the Kuiper Belt.

Discovery of the 10th planet!  Recent discovery.  Not much info. yet so no one can say if you are wrong on any point!

10 planets!!!These idiots don't even know what it is called!!!it's called "Sedna"
