My question is what is the approximate size (diameter) of this black-hole and what is its density. I assume its not particuarly dense just particuarly big.
Huh? It's a singularity, of course. You know, point-mass and all that, so it's very dense and very small.
But maybe you mean how far out is the event horizon? You can exactly calculate it from the mass of the black hole using R = 2 * G * M / c^2 where G is the gravitational constant, 6.67e-11, and c is the speed of light, 3e8. Since the Sun's mass is 1.989e30 kg, you can find this black holes mass by multiplying by 2.6e6. When I work out the radius of the event horizon, I get 7.7 million kilometers. From that you can calculate the "density" if you are still interested.
I bet you could have found all this out with this here Internet thing. After all, that's what it's here for.
