Terraforming

Here we go again. I'm doing NaNoWriMo this year (which is what I should be working on instead of a blog post), and because it takes place in part on Mars I've seemed to have fallen off the terraforming deep end again. I'll assume you know what terraforming means and dive right into it.

I really like the idea of terraforming other planets to make them habitable for humans. It's the most permanent solution to sustaining a larger human population. Mars and Venus are the most likely candidates, but I sometimes wonder: what if we terraformed every possible world in the Sol System?

Now, there's obviously this scenario, which is by authorial admission impossible. But there are a large number of potential terraforming candidates around. Let's go through the list and see what we think.
