    Did you try google searching? Google's search capabilities have made it a popular destination on the internet.

    I've heard good things about that Google program. Can I buy it at CompUSA?

    Google doesn't help much for what I'm looking for. I'm looking about when it was first discovered in 1995 by a Japanese amateur astronomer.

    I heard it's actually not that big (it was rumored to be twice as big as pluto, but I think Hubble discredited it).
    By the way I'm new here, so if anything goes wrong don't blame me.

    Whoops, forgot. Xena is said to be just a little bigger than pluto

    The 10th planet of the solar system is not a planet at all, just like pluto it is thought to be a satalite of a near by planet. Unofficially, it's called Quaoar (no pronunciation provided). Officially, it's '2002 LM60'. It's about 10 percent of earth's size

    I think there is a debate over whether it should be classified as an asteroid or a planet as its just a large hunk of rock and ice.

    edit:
    Of course the fact that they've already classified Pluto as a planet makes the debate a bit pointless.

    According to:

    http://www.telescopes.com/new-planet/index.php

    it is officially called 2003 UB313.

    unofficially it is called "Xena" not Quaoar.

    It is thought to be slightly larger than the moon. Therefore it could not possibly be 10% of earths size. it would be about a fifth of Earths size at 2400 KM. Moon's diameter is 3476 KM and Earth's is 12,756.3. (http://www.universetoday.com/am/publish/2003_ub313_large.html)

    More information can be found at the sites I provided, although I would trust the one about hubble (second one) more than the first one.

    It's conclusively proven that not just anyone could throw a baseball into orbit -- you'd have to have an excellent arm, so a professional pitcher could do it.

    Of course, just about anyone could wack a golfball into orbit.

    Also, even if Xena were about the size of the moon, it would be much easier there anyway since you wouldn't be fighting the additional gravity from the Earth and the sun.

    the gravitational fields of the earth and the sun are negilible on the moon man. at their most influencial they produce eliptical orbits and thats about it. thats like saying its harder to throw a baseball high in the sky at night than daytime. silly stuff ;)

    Fortunately, I still am a member of this board (Professor Emeritus), and let it be known that it is my pleasure to correct you all on this renowned (yet mysterious) "Planet X".

    This "10th Planet" was first discovered nearly 10,000 years ago by the ancient Sumarians. They counted the mystery planet as the "12th Planet", (alas, being ignorant primitives, they also counted the sun and moon as planets), but this planet is documented by them in many cuniform records and friezes
    (follow link below- scroll down to image of Sumarian Clay tablet depicting 10 planets in orbit around the sun).

    I think the debate now is not whether there's a 10th planet, but whether Pluto / Charon counts as a planet.

    there are lots of "planets" of that size discoverd so they just said that pluto and xena and al the others aren't planets

    Well, i don't think that they actually count as planets. If they're planets, i believe there are 54 other "bodies" that deserve to be planets too.

    they've classed them as dwarf planets i think.

    The criteria is that the body's gravitational field is big enough to shape it into a sphere.
