What is the current explanation for Earth's large Moon?
It likely formed just like the planets did around the Sun by gravity pulling the dust and gas into a tight solid sphere.

It was likely formed by a Mars-sized object which collided with Earth, while the material blasted out to space collected to form Moon.
