No, a typical white dwarf star is roughly the size of the Earth.
Neutrons star is the same size of a city. This is 10 km radius.
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
A white dwarf star is about the size of Earth.
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.
A neutron star is smaller, but has a greater mass. A typical white dwarf is about the size of a terrestrial planet. A typical neutron star is a few miles across.
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.
Depending on the size of the blue-white star it may be a white dwarf, a main sequence or even a supergiant star.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
Generally, they are not much bigger than the Earth.
No a white dwarf is a small compact star.
Several times smaller than our Sun. Details vary, depending on the type of dwarf star (a red dwarf and a white dwarf are quite different things), and the exact mass.
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
