Nobody knows what's actually in the Oort Cloud, however.

Rose Law firm billing records? Leaders who support J. F. Kerry? Another Heinz-Kerry vacation home?

Space exploration of this kind is a black hole into which billions of taxpayer dollars are sucked for absolutely NO useful reason. Who cares what is so far out in space that we could never reach it? Even if Sedna, a goofy PC name if I ever heard one, were an asteroid coming toward earth to demolish it, what could we do about it? Absolutely nothing. Couldn't all this research be put to better use than pursuing what equates to spending one's life making a giant ball of string?

[I still care]

Where did they get the name "Sedna" from?

The Kuiper Belt will turn out to be the steppingstones to the next star. It's going to take a while, but we'll work our way out until it's hard to tell if we're still in this system or the next one, and then work our way down into the next one. Got to watch your step, though, because the systems are moving relative to each other--like stepping off an escalator.

2004 topic, so reply at your own risk. ;') The July issue of "Astronomy Now" (a British mag, which is six months behind on its website) discusses the Nemesis theory in a breezy two page article (plus a couple pages of illustrations if memory serves), and Mike Brown doubts that Nemesis exists, but also entertains the possibility of some large body (such as the one discussed here) having been the agent for putting Sedna where it is. Brown's idea is, if more than one body like Sedna is found, orbit-wise, then it makes Nemesis more likely.

[BaBaStooey]

Michael Brown, the astronomer at California Institute of Technology who led the discovery of Sedna, said the most likely scenario involves the Sun having been born in a star cluster, and several stars that were then closer to the solar system -- still more than 10,000 AU away -- were responsible for ejecting objects like Sedna.

Hey, now, unless it involves Xenu, nobody wants to be hearing yer crazy crackpot theories, mmm kay!
