What is amazing that this is coming from a moon about the almost half the size of Ceres. That being said, and with Ceres possibly having a water vapor atmosphere, that little world needs a closer look. I can't wait for Dawn to get there.
This Hubble picture of Ceres reminds me of old Mars pictures. Are we going to be having discussions about how Mars-like Ceres is LOL!
Back to Enceladus, here is how it compairs to the Earth and Moon. 
Taken from this neat little site.
