Like people have already said mate, it's the 'slingshot effect' of the meteor's encounter with Earth's gravity.
It was dragged off it's original course by our gravity, but had enough velocity to not be captured by it.
Spacecraft designers make use of this phenomena to deliberately encounter a planet's or moon's gravity, to slingshot or catapult the spacecraft
onwards on a new course, and speed.
If they didn't the craft would not have enough fuel to carry out it's journey...the slingshot provides a speed boost, as well as course correction.
