On Pluto

This week Lily was learning about outer space at preschool. They wrapped up the week yesterday by going to our university’s planetarium (I didn’t realize we had one and it’s literally 5 minutes from my house!). On Monday, I started asking her about the planets and what she’d learned. I honestly wasn’t that sure anymore what was going on with them. I know at one point they decided Pluto was not a planet and then they found something else beyond Pluto, but I wasn’t sure if they’d classified THAT as a planet. And then I remembered more debate over whether or not Pluto was a planet. Was Pluto still a planet? Were there nine planets or ten or eight or what? I just wasn’t sure anymore.

I was trying to discuss it with my husband (but did not Google it for some reason) only to have him repeatedly declare “I don’t know and I don’t care!” Some scientist he is! Lily informed me that there were nine planets, but I wasn’t sure if the nine were the original nine I learned or nine minus Pluto plus that thing they found past Pluto, which Google tells me is called Eris. Who knew?

Anyway, I didn’t think Lily was paying any attention to me and my unresearched “Is Pluto still a planet?” debate when she came home from preschool yesterday and came straight up to me and said “Mommy, Pluto IS a planet!”

It is?

“Yes! There are nine planets! Pluto is VERY small, but it is a planet. It’s the last planet.”

I thought it was so cute and smart of her to not only remember that I wasn’t sure about this, but to confirm it for me.

Today Google tells me that some scientists have decided that Pluto is a planet again because it has its own moon. I can’t tell for sure if this is the official conclusion or if it is still up for debate. Google also tells me that Eris thing past Pluto IS a tenth planet, but I guess they aren’t teaching that in preschool just yet.

Our solar system was so much simpler when I was a kid!
