A planetary collision is exactly as bad as you would imagine. Unlike an asteroid impact, there's not just a crater left behind. Instead, such a massive crash causes the surviving world to be stripped of much of its lighter elements, leaving behind an overly dense core. Credit: NASA/JPL-Caltech

1.5 times the radius of Earth with a core that is 70% iron.

So, maybe on the order of 1 billion cubic miles of iron?

That's a whole lot of rebar and steel framed buildings.

Perhaps Tabby’s Star is the result of planetary collision and not a Dyson sphere.
