    en.wikipedia.org/wiki/White_dwarf

    A white dwarf is very dense: its mass is comparable to the Sun's and its volume Earth's. No nuclear fusion takes place in a white dwarf; what light it radiates is from its residual heat. [1] The nearest known white dwarf is Sirius B, at 8.6 light years, the smaller component of the Sirius binary star. There are currently thought to be eight ...

    Additionally, astronomers have found 6 white dwarfs (stars that have exhausted all fusible hydrogen), 21 brown dwarfs, as well as 1 sub-brown dwarf, WISE 0855−0714 (possibly a rogue planet). The closest system is Alpha Centauri , with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth.

  9. Sirius - Wikipedia

    en.wikipedia.org/wiki/Sirius

    Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The distance between the two varies between 8.2 and 31.5 astronomical units as they orbit every 50 years.
