A white dwarf is what remains of a star's interior, which is much hotter than the surface because it is closer to the source of fusion.
the sun, Pluto is a very cold dwarf planet, which is very small and was just recently proven a dwarf planet.
No, a black dwarf would have a fairly low temperature, for a star; scarcely hot enough to glow. Way hotter than a planet, but not all THAT much hotter.
No. The sun is a main sequence star. A black dwarf is the remnant of a dead star that has cooled. The universe is not old enough for this to have happened yet.
A white dwarf cooking into a black dwarf
A stars evolution. Our Sun will go yellow dwarf -> red giant -> white dwarf -> black dwarf.
Black is quite a hot colour when exposed to the sun
The Sun is currently a main-sequence star, which means it is in the stable phase of its life cycle where nuclear fusion in its core is converting hydrogen into helium. It will eventually evolve into a white dwarf, not a black dwarf, after exhausting its nuclear fuel.

A black horse absorbs more heat from the sun due to its dark color compared to a white horse, which reflects more sunlight. This makes the black horse feel hotter in the sun compared to the white horse.
No. The sun does not have enough mass to become a black hole. When the sun dies it will become a white dwarf.
The end of the Earth will probably come way before that. The Sun will get hotter and hotter for a while, and in about half a billion, or perhaps a billion years, it will get so hot that no life will be able to survive on Earth.
