Of these 68 stellar and substellar objects, only nine (about 13%) have an apparent magnitude less than 6.5, and thus can possibly be observed with the naked eye (the lower the apparent magnitude the brighter they appear to observers on Earth). These stars have their magnitude shown in light blue below. Besides the Sun, only three are first-magnitude stars: Alpha Centauri, Sirius, and Procyon. The classes of the stars and brown dwarfs are shown in the color of their spectral types (these colors are derived from conventional names for the spectral types and do not reflect the star's observed color). Some parallax and distance results were measured by the Research Consortium on Nearby Stars (RECONS), and these might be only preliminary measurements.
