What is Dark Matter?
This is the open question. There are many possibilities, and nobody really knows much about this yet. Here are a few of the many published suggestions, which are being currently hunted for by experimentalists all over the world. Remember, you need at least one baryonic candidate and one non-baryonic candidate to make everything work out, so there there may be more than one correct choice among the possibilities given here.
Normal matter which has so far eluded our gaze, such as:
dark galaxies
brown dwarfs
planetary material (rock, dust, etc.)
Massive Standard Model neutrinos. If any of the neutrinos are massive, then this could be the missing mass. On the other hand, if they are too heavy, as the purported 17 keV neutrino would have been, massive neutrinos create almost as many problems as they solve in this regard.
Exotica (See the Particle Zoo FAQ entry for some details.)

Going on the notion that there is indeed some sort of "mass object" perhaps affecting our solar system's gravity (e.g. Seismic activity on Earth, intense Sun activity, etc)

Agreed, but would it be going too far to postulate that there could be concentrated areas of dark matter?
and the whole freakin' universe is dark matter wherever there isn't something else
