It’s OK, now something interesting on Ceres:

“Largest Asteroid Might Contain More Fresh Water than Earth”

From :

[www.space.com]

I copy:

“Astronomers took 267 images of asteroid Ceres using the Hubble Space Telescope. From these images and subsequent computer simulations, they suggest Ceres may have a rocky inner core and a thin, dusty outer crust.
A team led by Peter Thomas of Cornell University said today that Ceres is nearly spherical, which suggests that gravity controls its shape. Also, the asteroid's non-uniform shape indicates that material is not evenly distributed throughout the inside.
These and other new clues, including Ceres' low density, point to an interior loaded with frozen water, the astronomers said. “

But somewhere else I read that Ceres might have originated somewhere in the neighbourhood of Pluto – meaning farther away from the Sun than Neptune.

So the scientists find it alien to it’s current position in our Solar system and also they have to resort to water so that they can explain it’s hollowness. Hm…
But the dimensions of Ceres strangely enough map the size of Neptune and it’s distance from the Sun. A smoking gun?
