If it was a black hole with the same mass as our sun has right now, nothing would happen. All the planets would maintain their present orbits. However, the radiation from a black hole with one solar mass would endanger all forms of life on Earth.

Mass is the only thing that effects gravitational pull and gravitational pull is what influences orbits. Therefore, a blackhole of equal mass as Sol (our sun) would have no direct effects on Earth's orbit. However, as the above posts have made clear, Earth would turn into a wasteland because blackholes can't function as an energy source like our lovely sun. Say goodbye to photosynthesis and your solar powered gadgets as well :-P

We'd all be dead within about 4 days.
Goandocmeback is wrong. There can be a black hole of the same mass as the sun, but it likeyl would not form naturally. Since this is all fantasy anyway, I assume same mass. If the black hole were the smallest required to form naturally, it would be about 3 times more massive than our sun. This would slowly move us into a far more elliptical orbit and perhaps pull us in after a few hundred orbits or so. But we would all still die within days anyway.

Without light from the sun, the earth would freeze over. But the orbit of the earth would not change because the mass would stay the same thus the gravity would be the same.
Goandcomeback: You are wrong and it is not nice to call other people names.

black hole sucks things around it in right? well we might or might not be sucked in. there would be no more summer only eternal winter where it would get as cold as pluto and life as we know it would end completly and we'd all die. and no, the heaters in our house and even the biggest of bonfires couldn't save us, the poorest homless people whould go first and the upper classes would only just be delaying the enevitable by cranking up the furnace. unless we were launched into space where e would starve to death. unless aliens really do exsist in which case they'd coem upduct us and keep us alive for experiments... hows that for an answer???

Disaster. The mass of a black hole is enormous compared to the sun's mass. Therefore, the earth's orbit would decrease in size substantially, perhaps even falling into the B.H., because the earth's orbital velocity is not high enough to maintain it's present orbit around a more massive core.

This cannot happen, as our Sun is not massive enough to end up as a black hole towards the end of its stellar life. Instead, it will end up as a white dwarf, another type of stellar dead body. The Sun is a yellow dwarf star right now.

It wouldn't change the earth's orbit, but we'd quickly freeze to death without the sun.

No more sunlight. All plant life dies. It gets freezing cold. All Life in the solar system would perish.

i think we might freeze!
