How large is a black dwarf?
The same size as the white dwarf it was. See related question.
What is the size of a white dwarf compared to?
A white dwarf has the approximate diameter of a moon, or a small planet.
Which is about the size of a city giant black hole white dwarf neutrons star?
Neutrons star is the same size of a city. This is 10 km radius.
What is the size of the black dwarf?
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.
Is a white dwarf smaller than Pluto?
A white dwarf could be smaller or bigger than the moon since it's size varies depending on the mass of the white dwarf. Since the mass of the moon is 7.347 x 1022 kg and the mass of Pluto is 1.31×1022 kg the size of a white dwarf is also smaller or bigger than Pluto depending on it's mass.

What is the size of a white dwarf compared to?
A white dwarf has the approximate diameter of a moon, or a small planet.
Is a white dwarf star about the size of a city?
No, a typical white dwarf star is roughly the size of the Earth.
Can winter white hamsters fit inside the habitrail ovo dwarf hamster habitat?
Why not, white winter hamsters are the same size possibly smaller than a dwarf hamster.
What is the maximum size of a white dwarf?
The maximum size of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. If a white dwarf exceeds this limit, it can collapse further and ignite as a supernova.
What happens to the size of a white dwarf when its mass is increased?
When the mass of a white dwarf increases, its size decreases. This is because the increased mass causes the white dwarf to contract under its own gravity, making it smaller and denser.
How much smaller is a white dwarf compared to its main sequence size?
A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.
Why would a supergiant have a brighter absolute magintude than a white dwarf?
A supergiant is much larger than a white dwarf. A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.
Which is about the size of a city giant black hole white dwarf neutrons star?
Neutrons star is the same size of a city. This is 10 km radius.
How does the the mass and size of a white dwarf compare with the mass and size of the sun?
A white dwarf, also called a degenerate dwarf, is a small star composed mostly of electron-degenerate matter. They are very dense; a white dwarf's mass is comparable to that of the Sun and its volume is comparable to that of the Earth.
Is the Sun a white dwarf before becoming its present size?
No. In about 7.5 billion years the Sun will become a white dwarf.
Is a white dwarf smaller than a red dwarf?
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
