I wish these sites would stop suggesting that Vesta is the second largest asteroid in the main belt. As far as I am aware, it is fractionally smaller than Pallas, although more massive.

Whilst checking for confirmation of the relative sizes of Vesta and Pallas, I noticed the interesting possibility that, if the Dawn spacecraft is fit and healthy after its mission at Ceres has been completed, it could be directed towards Pallas for a flyby when the asteroid crosses the ecliptic plane in 2018. Going into orbit would be impossible, due to the high orbital inclination of Pallas (34.8 degrees).

An interesting feature is the large dome at the centre of Vesta. Now how could that have been formed? :?

Yes, that is a very striking feature. It's amazing how every close encounter with a new object seems to reveal features that have never been seen before.

Above the dome there's a huge cliff-face. This looks to have resulted from slumping, with the slumped material piled up against the face.
