Researchers at the University of Zurich have claimed that Zwicky's theory of sun being surrounded by a dark matter is 99 percent certain and correct.

Interesting result for those sitting on a lump of dark matter reading this text.
This particular lump of dark matter is rather close to the sun and has an ambient average at cool room temperature.
Colder dark matter further from the sun is notoriously dark to see until it gets close enough to the sun to evaporate the volatile gas frost.
Also of interest here are the recent reports of "room temperature brown dwarves" which are parts of the Halo and thick disc component of the galaxy.
Objects smaller then the mass of Uranus will by now be rather difficult to distinguish from the microwave background at our distance from the galactic core.
Also note that the initial "globular cluster" stage of population 2 condensation with very low metallicity would produce droplets of condensing H, and He with masses ranging from a maximum of ~2.5 solar masses (hot enough to drive a nebula), down to objects of the mass of Uranus. Numerous smaller objects than Uranus mass embedded in the H & He rich molecular cloud would also be present but their descent into the crowded core of the globular cluster would evaporate most and cause a small percentage to collide & merge with larger objects in the "pinball machine zone" in the core.
A lot of the dark matter in the Galaxy today would be remnants of this early condenstation stage forming the dark matter halo. Objects smaller than Uranus mass would not survive long in the galactic bulge of modern times.
Then of course consider current gas/dust condensation comets kicked out of a planetary system by orbital encounters with a big gas giant. This last mechanism will be responsible for much of the cold dark matter in the galactic disc featuring a lot of mass with a small diameter easy to see round.
