How big can a black dwarf planet get?

When a star becomes a black dwarf it?
In that case, it will basically stop emitting any radiation. No star has had time so far to become a black dwarf - the Universe is too young for that. This is because it takes a white dwarf a long, long time to cool down.
How long is the Sun's life expectancy?
It should "live" for about 5 billion years as it is, more or less. Then it will become a red giant star. Then it becomes a white dwarf. Finally it will "die" as a black dwarf.

Is a dead star the some as a black dwarf?
No, a dead star is different from a black dwarf. A black dwarf is a type of stellar remnant, but not all stars become black dwarfs. When a star dies it will leave behind a white dwarf, a neutron star, or a black dwarf as a remnant depending on its mass. Given enough time a white dwarf will eventually cool to a black dwarf. The universe is not old enough for this cooling to have happened yet.
What comes before white dwarf and after white dwarf?
Before a white dwarf, a star would undergo the red giant phase. After a white dwarf, a star may end its life cycle as a black dwarf, although no black dwarfs are currently known to exist in the universe due to the long timescales required for a white dwarf to cool down.
Steps in the life of a star?
