Note that early type stars are rare, but are bright, and so we notice them readily. On the other hand, late type stars are numerous, but faint, and so we do NOT notice them readily. In fact, NO main-sequence M star can be seen by the naked eye (see Wikipedia: Class M), NOT even Proxima Centauri (distance 1.30197 pc = 4.2465(3) ly) the closest neighbor star to the Sun.
