We have not found it in the solar system yet.

So, I suggest two experiments to find it.

Till finding the Dark Matter, any theory could be a speculation.

The key point is an using a metalic hydrogen as a Dark Matter detector.

Metalic hydrogen has many nucleus per unit volume.

But, making a lot of metalic hydrogen is practically not easy.
So, observing the metalic hydrogen planet is , I think, more easy to find the Dark Matter.

If there are(were) Dark Matter in the solar system, the Dark Matter can(could) not pass through the high density planet without any interactions.

The Neptune has more high heat flux than that of the Uranus.

What is the cause of this phenomena?
