No; actually, white dwarves are rather dim.
Red giant is the largest and the brightest.
No. It is the brightest star in Andromeda; a white dwarf won't even be visible with the naked eye, even if it fairly close to us, such as Sirius B.
Yes, some of the 20 nearest stars are white dwarfs. For example, Sirius B, the companion star to Sirius A, is a white dwarf. Among the 20 brightest stars, Sirius B is the only white dwarf.
The brightest star in Canis Minor is Procyon. It is a binary star system consisting of a main sequence star and a white dwarf. Procyon is visible in the northern hemisphere and is the eighth-brightest star in the night sky overall.
Not exactly. A white dwarf would be hard to see from Earth, and Sirius is the brightest star from our point of view. Sirius has two components; one of them, Sirius B, is a white dwarf.
Polaris is not a white dwarf. If it was you wouldn't be able to see it. Polaris is in fact a multiple star system, that just looks like one star. The brightest star is a bright giant with a spectral type of F7 - so it will appear as a yellow-white star.
Acubens is a double star system located in the constellation Cancer. The primary star, Alpha Cancri A, is a yellow-white dwarf star with a color temperature of around 6,177 K. The secondary star, Alpha Cancri B, is a white dwarf star.
The brightest star in the constellation Hercules is Kornephoros, which has a white color.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
No a white dwarf is a small compact star.
No, Sirius is not an asteroid. Sirius is a binary star system consisting of the brighter star, Sirius A, and its companion, Sirius B, which is a white dwarf star. It is the brightest star in the Earth's night sky.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
