In the case of these relatively dim and difficult to study stars, we should examine first the inner sphere of space within 50 ly of Sol. Within that enormous sphere, astronomers have detected at least 7.38 Solar-masses of visible matter bound up in 11 luminous stars and one weakly glowing white dwarf. At least two-thirds (88+ or 66+ percent) of the 150 or so objects found thus far to be located within 20 light-years are very dim red dwarfs, of which at least 39 (roughly half) may be flare stars and are likely to be relatively younger. lane of dust which gives this nebula its name.
