How many planets?


Remember when we were in school and were taught that there are nine planets? I guess that is still true, but only of our solar system. No, wait, I just read that Pluto is no longer considered a planet! What has been discovered is that there are many, many solar systems, each with many, many planets. How many have they found now? This article says scientists have found a super-Earth which is near the right distance from its star to hold water. It is one of over fifty new planets found this month alone. There was another one of these "super-Earths found in 2007.

Update: This article
says there may be 16 "super-Earths!"

I totally believe there are many sustainable planets out there. We have only just begun space exploration and yet only just begun to stop our forward motion. Sad that.
