Is Ceres from the Kuiper Belt???

Whoa, here's a new theory for you:

AN IMPOSTER!!

Hmmm this is pretty intresting to be honest. The lower density is indeed odd. There are asteriods that have densities that are somewhat similair but there alot smaller than ceres is...

Heh, a Plutoid took over the asteroid belt. Course, even if they proved it, they wouldn't call it a Plutoid.

It's too early to speculate. We don't have enough information. Like the article said, even Dawn won't be able answer the question with any certainty. The answer will come from a mission beyond Dawn, to measure the actual isotopes.

I have significant doubts; but nonetheless, the idea is interesting.

Just wondering...

Dutch astronomer Gerard Kuiper theorized the
existance of the Kuiper Belt with distance objects at the edge of the solar
system. Comets’ orbits seem to indicate that the Kuiper Belt is their source of
origin and the discovery of 1992 QB1 stands as the first observational evidence
for the existence of the Kuiper Belt.

Other than de HST confirmation of KBOs, which other
observational evidence do we have on the existence of a Kuiperbelt beyond 50
Astronomical Units?



Is there any observational evidence of a similar belt
around nearby stars?

HD 107146, q1 Eridani, Vega, 61 Virginis, AA Tauri, AB Aurigae, HD 97048, Epsilon Eridani, Fomalhaut, HD 32297, HD 38529, and AU Microscopii (just to name a few) have circumstellar disk material beyond 50 AU. Many of the disks are resolved.
