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.
Dwarf galaxies merely refer to the size of the galaxy itself, not the stars in the galaxy, so no.
Dwarf stars are died stars , they are about the size of earth and has a temperature of about 10 000 C (18 000 F).
Dwarf stars are died stars , they are about the size of earth and has a temperature of about 10 000 C (18 000 F).
Red and White dwarf stars.
Little stars, also known as dwarf stars, can range in size from about one-tenth the size of our sun to around half the size of our sun. These stars are smaller and cooler than average stars like our sun.
A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
The five main groups of stars are main sequence stars, giant stars, supergiant stars, white dwarf stars, and neutron stars. These groups are classified based on their size, temperature, and stage in their life cycle.
The Sun is a classed as a yellow dwarf. That's a typical size for these stars. The term dwarf is a bit misleading here. The Sun is much larger than a red dwarf star, for example.
A white dwarf is very small as stars go; comparable in size to a small planet such as Earth.
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.
There are billions of red dwarf stars. I will name just one and it's the nearest star (apart from the Sun). That red dwarf star is the famous "Proxima Centauri".
A star on "main sequence" is a period in a stars evolution.A white dwarf is a stellar remainA supergiant star is the size of a very big star.So they are completely different and not even related.
