Question

Why is Mercury's orbit so fast?

Answer 1

Hey dude,

These oscillations, or librations, are caused by the planet's interactions with the sun as it moves around the star. The sun's gravitational pull speeds up or slows down Mercury's rotation depending on where the oblong-shaped planet is on its elliptical orbit.
