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.
No, a typical white dwarf star is roughly the size of the Earth.
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.
Pluto is not a star. It was never declared a star. It is a dwarf planet. It had been regarded as a planet, but due to its size and its orbit, it is now classified as a dwarf planet, but not a star.
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.
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.
dwarf star
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
It is a red dwarf star with a diameter that is about 14% of the Sun's.
Generally, they are not much bigger than the Earth.
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.
Neutrons star is the same size of a city. This is 10 km radius.
