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.

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


That might be a white dwarf.


A white dwarf is hot and dim because it is small, a small star is dimmer than larger stars.


Relative heat and distance - they're small. Hot translates into color -- white hot. Dim is how much light reaches us.


A white dwarf is hot, but has a very small surface area compared to a main sequence star, which limits how much light it can produce.


White dwarf stars are the dead remnants of stars that were no larger than our Sun. While hot and bright, they are no longer producing new energy and are gradually cooling down to become "black dwarf" stars. White Dwarf Stars are all small about the same size as the Earth and thus while their surfaces are hot, they do not radiate from a large surface area and thus appear dim from a distance.


Because they are small, usually about the size of the Earth and thus difficult to see.


A white dwarf star is the remaining core of a dead star, so it is extremely hot. The star is also dim because it is small, so it doesn't emit a lot of light in comparison to other stars.


There could be many answers as dim and hot are mutually exclusiveBrightness (or dimness for that matter) is defined as a stars luminosity and it's distance from the observer.So a hot star could be very far away and appear dim, whereas if it was relatively close, it would appear bright.A hot but small star, would appear dim at a close distance.However, in all likelihood the answer you might be looking for is either:Neutron Star - Very small and very hotWhite Dwarf - Small and very hot


The brightness of a star depends (a) on its temperature, which affects the amount of radiation emitted per square meter, and (b) the total surface area. A white dwarf has a very small surface area - around 1 / 10,000 the area of our Sun.White dwarf stars are the compressed cores of a dead star, so it is very hot. Since a white dwarf is also small, it emits less light than most stars, so they are dim.


Dwarf stars are dim because they are small, so their luminosity (amount of emitted energy) is low compared to other stars, and low luminosity means more dimness.


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.


White dwarfs are dim because they are small, and small stars radiate less light.


No; actually, white dwarves are rather dim.


A white dwarf star can be as hot as 150,000 degrees kelvin.


Yes, if it is close enough. Dwarf stars aren't especialy bright, but they are quite common. Many of the dim stars that you see in the sky at night are dwarf stars.


While they are hot, white dwarfs are very small compared to other stars and therefore have a much smaller surface area fro which to emit light. Therefore the total amount of light they emit is relatively small.


A red dwarf star is hard to see because those stars are small and dim, their low luminosity made them hard to observe.


The nearest dwarf star is Proxima Centauri, about 4.24 light years away and so dim it can't be seen in binoculars.


15.49. Proxima Centauri is a red dwarf, and therefore rather dim.


No. Dwarf stars are very dim. A good example is Proxima Centauri. That star is the closest to the Earth but still invisible to the naked eye.


They are hot because they are the stellar remnant of a star, they are also very small, about the size of the Earth, and because of that they appear to us as being dim.


Impossible to answer because they are dim stars so we can only see the close ones.


Red dwarf stars may be the most common stars throughout the galaxy, and possibly the universe. They are so dim, however, that they are difficult to see.The red dwarf Proxima Centauri is the closest star to our Sun; however, it is not visible without a telescope. Doubtless there are a great number of stars further away that are entirely lost to view because they are so dim.If two stars have approximately equal apparent magnitudes, the dim & tiny red dwarf star is far closer than the enormous red giant.


No. While a red dwarf star is quite dim compared to the sun. Viewed from up close, such a star would still be blindingly bright.
