Like all the other matter, the Milky Way’s dark matter is zipping around at a fair clip. Not interacting means that dark matter orbits galaxies in puffy, roughly spherical “dark matter halos”; a cloud of randomly orbiting stuff that barely notices all of the stars it passes by/through. So if you gathered up all of the dark matter in the Earth (or an empty Earth-sized volume, for all that dark matter cares) you’d have a bit less than 1 kg. If dark matter particles are neutrino-sized, then you presently overlap with at least 75 trillion of them. “There’s dark matter in me right now!” is a great conversation starter and ender, but that’s about the extent of its personal relevance.
