Re: APOD: Dark Craters and Bright Spots on... (2015 Feb 18)
Thanks for the info on the estimated density of Ceres. It is quite a bit bigger and it is still less dense than Io and Mars at 2.077 g/cm^3. If it properly compacted like other planets, it would be more dense than Io and less dense or comparable to Mars. I feel that I have fleshed out details of my...

... Smithereens did not get to fully compact (like other planets) prior to the crash, this accounts for the density of Comet 67P, and I predict that Ceres will have a similar density (plus or minus 15%). ... Well, there's a lot of creative speculation in your post. It's fun discussion with colorful...

Ice - perhaps an ice layer rather than ice lakes. The asteroid belt, including Ceres, is the result of a big crash as a planet was trying to form. Another planet had formed between Jupiter and this one, I call it Illo. Then when the protoplanet between Illo and Mars (I call Smithereens) tried to for...
