How about this:

Fractus, also known as the Sundered World, is a lifeless planet known for the fact that the entire world has been split in half, and yet somehow the broken planet maintains a gravitational pull. Pieces of it's own landmass float around it, often crashing into it's surface, surrounding Fractus in it's own asteroid field. Rumors say that Fractus is home to lost Archotech, prompting many an Adeptus Mechanicus Explorator to visit the Sundered World, but the amount of debris that routinely crash into it's surface makes it extremely dangerous to do so.
