There is dark matter in the Sun, but the density of dark matter within the sun is not so much greater than the density across the solar system as a whole. This is in contrast to ordinary matter, where the sun represents the overwhelming majority of the mass of the solar system.

This is precisely the problem with Dark Matter! First you have to explain that somehow DM doesn't interact with either itself or with Regular Matter other than through gravity. If it starts falling into a star's gravity well, it will just slingshot out again since there is no force there to brake it.

Why would dark matter fall in as opposed to following an keplarian
orbit?
