A neutron star is a star that has collapsed almost to the point of being a black hole. It would be like taking the sun with all its mass and shrinking it down to the size of a small city (except it would be a sphere with diameter of 10 miles). All that mass packed in a tiny volume makes the matter very dense. About as dense as you can get without getting a blackhole. The fact I remember from class is that just one TEASPOON of the matter on a neutron star would weigh 1 TON on earth. Hope this helps.

For normal matter, it is a runoff between element 76 (osmium) and element 77 (iridium) with a density of about 22.5 grams/cc (as compared to water with a density of 1 gram/cc).
If compressed, matter can become even more dense. A human placed under the pressure of Jupiter's core would collapse to the size of a mouse, and the density would increase also- the same amount of mass would be present, making the person have a density of about 1500 grams/cc.
For the densest matter known, burned out neutron stars are just about at the limit, with density of about 10^15 grams/cc (which is 1,000,000,000,000,000 grams/cc). A one centimeter cube of this matter, which is called neutronium, would weigh as much as a cube of water a kilometer on a side.
Some pulsars are about 300 times more dense that this, and the highest density is found in black holes- although they are not exactly matter, they are a boundary where light cannot escape. Still, a small black hole would be the "densest object". Larger black holes paradoxically have lower densities.

Aside from a Black Hole, the element osmium which has a density of 22.48 gr/c3.
Hope this helps!

Black holes are odd singularities whose boundaries are ill-defined. Neutron stars are pretty well understood, though. Their densities are greater than 10^13 gm/cm^3: http://en.wikipedia.org/wiki/Neutron_star
By comparison, osmium is a measley 22.6 gm/cm^3: http://en.wikipedia.org/wiki/Osmium

platinum.....It's dense but not sure what would be more dense.
