    How hard is it to detect stars say of a tenth the solar mass, I know it depends on the distance of course, but how frequently do we spot these kind of stars ,moreless?

    Hi there,

    As star in the primo sense is an object that emits light. Therefore, it should not be to hard to detect stars, even small ones.

    If you look at this list of the 100 nearest stars, over 50% have <0.20 solar masses. These types of stars are quite common, but become difficult to detect as they get further away because they are intrinsically so dim.

    The vast majority of stars are believed to be M class, or lower mass. These tiny furnaces will outlive our own sun by many billions of years.
