There Are 9. No, 12. No, 56.

Further to my post below about getting old, now I have to remember that there are 12 planets (and maybe dozens more) not the 9 I learned when I was a kid. What's an old fart to do?

But, I guess I won't be the only one having this problem.

Asked what planet Superman was from, 60 percent named the fictional planet Krypton, while only 37 percent knew that Mercury is the planet closest to the sun.
