Your pix reminds me of Sitchin's mythtalk and is similar to Tiamat getting side-swiped by Marduk (Nibiru). The collision takes place in the asteroid belt during one of Marduk's 3,600-year orbits, shattering half of the planet which caused the asteroid belt, and pushing the other half into an orbit between Mars and Venus, later becoming Earth.

The moon was one of the larger bodies orbiting Tiamat and was captured by Marduk after the collision, but only briefly, as it joined with Earth to share the new orbit of the remains of Tiamat. The center of balance (I forget what it's called) is a mile or two beneath the Earth's surface.

There is, alas, no Marduk and there was no Tiamat. :’)
