I assume you mean a DWARF STAR. There are different types of dwarf stars; the white dwarfs are fairly hot - but the reason they are dim is that they have a very small surface area.
That might be a white dwarf.
As the name white dwarf implies, this is a small type of star, and it has less surface area from which to radiate light, so even if it is hot, and giving off lots of light per square mile, there are fewer square miles than in larger, non-dwarf stars, so there is less total light being emitted.
a white dwarf
Dwarf stars are dim because they are smaller and cooler than other types of stars. Their lower temperature and smaller surface area result in less light being emitted compared to larger, hotter stars. This makes them appear dimmer when observed from a distance.
Impossible to answer because they are dim stars so we can only see the close ones.

White Dwarf Stars are very hot, like a ball of fire. They are dim because they are small and very far away.

No; actually, white dwarves are rather dim.

The nearest dwarf star is Proxima Centauri, about 4.24 light years away and so dim it can't be seen in binoculars.
A red dwarf star is hard to see because those stars are small and dim, their low luminosity made them hard to observe.

This describes a white dwarf, which is a small, dense star that remains after a star has exhausted its nuclear fuel and shed its outer layers. White dwarfs emit heat and light as they slowly cool down over billions of years.
