A black dwarf is any stellar remnant, that has cooled completely, so that no radiation is emitted.
They - at the moment - do not exist, as the Universe has not been around long enough for any stellar remnant to cool to this state.
A black dwarf would - if it existed - be anywhere from the size of a city (Neutron star) up to 1.4 times larger than the Earth.
