A star's radius is the distance from it centre to its visible surface. The bigger the star, the larger the radius. The radius is not the best means of comparing stars, it is perhaps better to compare stars by their mass.
Average is about .01 Solar Radii. Oddly enough, the higher the mass of the White Dwarf, the smaller the radius
They produce light.
There are more low mass stars. this is for two reasons:- # the star forming process generates more low mass stars # High mass stars burn out very quickly and explode as supernovas and thus over time there are less and less of them.
There are three types of stellar remnants. Low to medium mass stars will become white dwarfs. High mass stars will become neutron stars. Very high mass stars will become black holes.
Typically,giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun.Whereas Supergiants have a radii between 30 and 1,000 solar radii and luminosities between 30,000 and 100,000 times that of the Sun
-- If your mass is 'm', then your mass is 'm', regardless of whether you're on the earth,2 earth radii out in space, or on the moon. Mass doesn't change.-- On the surface, your distance from the center of the earth is 1 earth radius. Weight isinversely proportional to the square of the distance from the center of the earth, so at adistance of 3 earth radii from the center, your weight is 1/32 = 1/9th of your weight on thesurface. If your mass is 'm' then your weight on the surface is mg = 9.8m newtons, and at3 earth radii from the center it's 1.089m newtons (rounded).

The universe is a much more complicated place than you seem to believe.The radius of a white dwarf star (I assume you mean a degenerate dwarf, not a main sequence star that happens to be white, which could also be called a "white dwarf") depends on its mass. An interesting property is that higher-mass stars have smallerradii.While we can't provide "an exact number in kilometers" (or any other unit), we can say that the majority of white dwarfs have radii between 0.008 and 0.02 solar radii (5600 to 14000 kilometers).
An isolated and distinct mass of stars is a galaxy.
its not about stars its about mass and he proposed that mass can be converted into energy
They produce light.
Higher mass stars "burn" faster due to the increased pressure in the core.
In a newly formed star cluster stars with low masses must greaty out number stars with high masses. High mass stars are rare and low mass stars are extremely common.
