Mercury once collided with large asteroids?
Mercury once collided with a large asteroid, which caused the planet to slow down, while also causing it to change its direction in the opposite direction to the Sun.

Discovering the planet in paradox
Astronomers in the UK have found the first planet to turn against its own star. The star forms when a cloud of dust and gas shrinks, causing its own mass to increase
