Wow. I was in middle school and had to do a creative writing assignment, and I wrote a science fiction short story set in a colony on that boundary of Mercury. I thought Mercury was tidal locked. I was praised for my creativity.

I was today years old when I found that Mercury is not tidal locked.

Same here. I was so going to ackchyually that guy, but I did a quick check before and turns out there is a day/night cycle.

Apparently one Mercury day takes exactly two Mercury years due to some fuckery involving "3:2 spin-orbit resonance" which is something I'm too drunk to comprehend right now.

Gonna be an interesting wikipedia binge at work tomorrow tho

The 3:2 resonance Klear references is considered a type of tidal locking.
