Was it worth it?
I have a general astronomy question.
If earth is something like 6 times, in volume, the moon has, then why does it seem that the earth, when looking at it from the moon, seem to look about the same size as the moon does from the Earth?
Wait just a darned minute!! I saw “John Carter” and it didn’t look that way in the movie.
Very cool.
It's a planet-sized selfie!
