Planets other than Earth

Been a lot of talk about extrasolar planets lately...

In the past week, Space.com has reported about both <a target="_blank" href="http://www.space.com/scienceastronomy/super_earth_040825.html">a "giant Earth"</a> and <a target="_blank" href="http://www.space.com/scienceastronomy/exoplanet_pair_040831.html">two Neptune-sized planets</a> being found. So, there's been a lot of talk about voyages to other planets and finding other Earths lately. I think we'll eventually go, but it'll be in generation ships and things on Earth will have to get really desperate first. After all, that would be a "one-way" trip.
That's nice and all, but I think they're missing the boat in some ways. I mean, why not inhabitable moons? <a target="_blank" href="http://www.space.com/scienceastronomy/shadow_moons_021008-1.html">Accor… to Space.com</a>, they could very well exist. In fact, I speculated on that quite some time ago and I even got a physist to back me up! A very nice man by the name of Sheridan Simon, who's also done work for <a target="_blank" href="http://www.ethshar.com/">Lawrence Watt-Evans</a>, did up a whole planetary system for me. I actually based it around Tau Ceti, which he said was a good choice, actually, since it's very similar to our own star. Anyway, he did up a whole system for me. I ought to scan it and make it available on-line... Well, we'll see about that, but it is an interesting line of thought for science-fiction, isn't it?
Read the articles, think, then write! Go on!
