What does a White Dwarf eventually become after cooling down for billions of years?
Answer
Black Dwarf
After a low-mass star sheds its outer layers, the remaining hot, dense core is known as a white dwarf. Because it no longer performs nuclear fusion, it only glows due to leftover heat. As it radiates this heat into space over an immense duration, it gradually cools down until it eventually becomes a dark, cold, and inert object referred to as a black dwarf.
