A black dwarf would be about the same size as a terrestrial planet such as Earth, so it would be larger than some planets but smaller than others.
A black dwarf is not a planet; it is the remnant of a long dead star that has cooled. A black dwarf would range from about 7,000 to 17,000 miles in diameter.
A neutron star is smaller, but has a greater mass. A typical white dwarf is about the size of a terrestrial planet. A typical neutron star is a few miles across.

If a dwarf star crashed into a planet,the planet would likely explode.
It depends on the size of the star. You could end up with a White Dwarf, a Neutron Star, or a Black Hole with a White Dwarf coming from the smaller star and and a Black Hole coming from the largest star. Our Sun will leave a White Dwarf when it burns out.
Pluto is not a white dwarf star, it is just a dwarf planet.
None. A yellow dwarf is a type of star, not a planet. The sun is a yellow dwarf.
Pluto is not a star. It was never declared a star. It is a dwarf planet. It had been regarded as a planet, but due to its size and its orbit, it is now classified as a dwarf planet, but not a star.
Depending on size, and some other factors, that can be a planet, a dwarf planet, an asteroid, or a meteor. Depending how you look at it, you might or might not include moons (they orbit a planet, and together, planet and moons orbit the star).
No. Eris is a dwarf planet.
A black dwarf does not burn anything. A black dwarf is the cooled remnant of a dead star.
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.
