Another Correction
I referred to recently discovered planetoid Sedna yesterday as a Kuiper Belt Object, but this article today states that Sedna may actually lie beyond the Kuiper Belt, within the Oort Cloud, believed to be where most comets spent the majority of their orbital period. Addendum: To give an idea of just how far away this thing is, one of the Voyager probes was recently reported to have reached "the edge of the Solar System" at 90 AU out. Sedna, on the other hand, is somewhere around 900 AU at the farthest point in it orbit (although it's currently at only about a tenth of that), which is about 1.4 percent of a lightyear (by my liberal arts calculations). Addendum:Great. Just Great: "Sedna also may have a tiny moon, but if such a satellite exists, only the Hubble Space Telescope would be able to detect it. Hubble is also the best tool to determine Sedna's actual composition and mass, Brown said." Following the announcement, NASA Administrator Sean O'Keefe was hanged in effigy, NASA centers set on fire, and launch vehicles overturned in the streets. Can we just move on, people?
