[utglyvmo] dark matter cloud

what would we observe if the earth, or the solar system, passed though a dense cloud of dark matter?

assume WIMP.  we would see not the dark matter directly but only indirect effects.  hypothesize that orbits will change.  will the sun gravitationally capture dark matter and increase in mass, increasing its fusion rate?

do dense clouds of dark matter exist?  how dense might they be?
