Earths dark matter is equivalent to one squirrel.

Right, but even that link suggests dark matter is pretty homogeneous around Solar System, right? If it’s simply described as a density number.

Is the suggested experiment just measuring that homogeneous density? Or hoping to find some distribution around the Solae System?

We've only been able to infer dark matter densities over galactic scales so I'm not sure that density applies at planetary system scales. It's like trying to use the density of iron to say where the atoms in a chunk of it are.
