So, because I have way too much time, and not many CTPs, on my hands, I figured that I would take a couple of hours and put together a Spreadsheet that lays out mathematically generated prices for Artifact Planets based on Size and Abundance. I will use this Spreadsheet in my future requests when looking to buy and sell Artifact Planets, and hopefully some of the more experienced members on here may find it nifty as well.

So, here's the link to the Document, and the last page (with the colorful green spreadsheet) has the prices:

Now, so this post has a purpose on the Trading Post, I'm looking to buy any planets that fall in the following image's highlighted range. PM me and we'll arrange.

If anybody's any bit interested in the math, feel free to ask!
