In second grade my teacher whacked me on the leg with a ruler.
This happened because she said, "There are nine planets" and I said, "Silly! There are hundreds of planets, we just haven't found them all yet."
She said the smack was for calling her silly. She insisted there are nine planets. Ever. Anywhere.
Obviously, she meant in the solar system (Poor Pluto). But she didn't say that.
ANYway, check this out. Important bit:
"There's at least 100 billion planets in the galaxy—just our galaxy," says John Johnson, assistant professor of planetary astronomy at Caltech and coauthor of the study, which was recently accepted for publication in the Astrophysical Journal. "That's mind-boggling."
HA! So there. Meanie.
