I heard when a star's life comes to ends, it becomes Dark hole. Sun is also a star. If Sun's life comes to ends, will it become Dark Hole? If so, Will it suck nearby planets like Mercury, Earth?
Sorry about my English.

"...I heard when a star's life comes to ends, it becomes Dark hole..."
Not all stars become black holes. Only those that are about 10 times more massive than our own sun end up as black holes.
"...If Sun's life comes to ends, will it become Dark Hole?..."
No, the sun won't become a black hole. It would have to be about 10 times more massive than it is to end its life like that.
Even if the sun was a black hole right now it wouldn't suck in any of the solar system's planets. Its mass would be exactly the same as it is now. However, if some planet somehow wandered out of its orbit and got too close to the sun/black hole it could easily be sucked in.

The closest black hole to the Earth is more than 1600 light years distance from the Solar System in our own Milky Way Galaxy. That's much closer than the multi-million solar mass black hole at the center of our Galaxy. The center is 23,000 to 26,000 light years distant from the Solar System.
The Sun does not have nearly enough mass to even become a neutron star, much less a black hole.It will eventually create a planetary nebula and become a white dwarf and slowly cool to become a black dwarf star. There are already red-dwarf stars that still have not become black dwarf stars because it takes TRILLIONS of years for that to happen, and the Universe is only 13.7 to 14 BILLION years old.
It will take at least 2.5 billion years to 4.5 billion years for the Sun to start expanding into a red giant star. Different web-sites give different numbers of billion of years for the expansion to start. I don't remember now what person, business or university, the web-site with the 2 to 2.5 billion years
