Don't know much about......astronomy

Ok, I admit, science is NOT my area of expertise. I have never enjoyed it and don't pretend to now. Science is daddy's department. I handle those pesky take-home English tests. So, it's clear that Payton did not get his love of science from me! He is studying the solar system in fourth grade right now, and tonight, on the way home from basketball practice, he was sharing some of what he's learned.

Payton: "Mom, do you know what the biggest planet is?"
Me: (Wracking my brain and hoping for the best!) "Hmmm, I think it's Saturn or Jupiter."
Payton: "Oh yes, it's one of those."
Me: (BIG sigh of relief....)
Payton: "Mom, did you know that when you compare the sun to us, we are an olive and Jupiter is a grapefruit?"
Me: (picturing myself as an olive, then gratefully realizing that he meant the "earth") "Nope, didn't know that either!"
