I started my Uni course this week. My first one, the lecturer said “There are only 8 planets. I know you’ve all grown up hearing about 9, but Pluto was reclassified.”
My newest lecturer today said “Pluto was reclassified a few years back.”
I didn’t know how to tell them that no, I didn’t grow up hearing about it. Pluto was reclassified before I was born. The second lecturer wasn’t even that old, probably a millennial.
That really threw me off. But apart from that, I’m loving Astronomy, it’s a very interesting subject!
