"You know... I was thinking about something", Aaron began as we drove home from school today.
"What's that, buddy?" I asked.
"Can you believe the moon is only a satellite?"
"It's interesting, isn't it?" I said.
"Yes, because the Earth orbits the sun. It goes around and around and around. But the moon only orbits the Earth. Why doesn't the Earth and moon fly away from the sun?"
"Because.... ummm.... because the sun keeps the Earth in its orbital path with the pull of its gravity."
"Why doesn't the sun just pull the moon to itself so it will orbit the sun and be a planet too?"
SERIOUSLY?!?!?! I can't keep up with this kid. It went on from there, but I will stick to the short version.
Thank you Jen, for Earth and Sky---the book you gave Aaron last Christmas. Next time we have a solar system question I am having him call you rather than having him google with me! :)
