Detailed explanation-1: -Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun. As this computer simulation shows, the planets would actually continue on in their orbits as if nothing had happened.
Detailed explanation-2: -Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them.
Detailed explanation-3: -No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf-a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
