Space Studies Tuesday: Lesson 2-1 Reference Systems

I had no idea the orbit of the earth was so complex until I saw this video:

I'm thinking that if you want to do some major time travel, like they did in Terra Nova, you have got some serious positional calculations to make, too.  No wonder they ended up with an alternate dimension Earth.  (Terra Nova was a pretty good show, too.  Too bad it got canceled.)

I don't have a lot of comments on this section.  It was mostly vocabulary, and I've got the feeling I'll only truly grok it if we use it in later lessons.  I will remember to come back to it, however. 

Was any of this new to you?
