At what point in time will the sun become a black dwarf? A trillion years?

The sun is not expected to become a black dwarf for another 10 trillion years.
A black dwarf is a theoretical celestial object that is formed when a white dwarf star has completely cooled down and no longer emits heat or light.
As the sun runs out of hydrogen fuel, it will expand into a red giant and eventually shed its outer layers, leaving behind a hot, dense core known as a white dwarf. Over time, this white dwarf will cool down and become a black dwarf.
No, it is predicted that the Earth will be destroyed long before the sun becomes a black dwarf. As the sun expands into a red giant, it will swallow up the inner planets, including Earth.
Since black dwarfs do not emit heat or light, they will have little effect on the rest of the solar system. However, the loss of the sun's gravitational pull could cause the remaining planets to drift away or collide with each other.
