Hyperdense Object

If a planet has a core of super-dense material, how might that effect the geological composition of that planet?

Specifically: imagine a lunar-sized planet, with earth-like geology and density. If the center of that planet is a very small mass of super-dense unobtanium that cannot collapse in on itself (think neutron star density. This Super dense material is about 97.3% of earths mass compressed into the size of a shower stall), how would that effect the surrounding layers of this planet?

Would the normally earth-dense layers just flatten against the core and the rest of it become super-dense as well?

Would this planet be able to hold liquid water and an atmosphere?

Thanks for the feedback.
