How Does Something Really Weird is Happening on Mercury - no bs Work?

Something really weird is happening on Mercury because it spins around its axis super fast sometimes and super slow other times, kind of like how you spin a toy top.

Imagine spinning your favorite toy top on the floor. When it's going super fast, it stays nice and steady, right? But if you give it a little nudge or make it go slower, it starts to wobble, maybe even tips over!

Mercury is like that toy top. It has a weird kind of spin called precession. This means Mercury doesn’t just go around the Sun in a perfect circle, sometimes it leans forward, then backward, making its orbit look like a squiggly line instead of a straight one.

Now think about when you're on a swing. If someone pushes you at just the right time, you go higher! Mercury gets pushed by gravity from the Sun, but not in a simple way. It’s like getting nudged every now and then, making its spin speed change.

This makes Mercury's days and years feel super weird, sometimes it takes longer to turn around once than other times!

So even though Mercury is super close to the Sun, it’s doing something really cool with its spins, no magic, just gravity playing a little game.
