See reader questions & answers on this topic! - Help others by sharing your knowledge Obvious candidates are alpha Orionis (Betelgeuse, M1-2 Ia-Iab), alpha Scorpii (Antares, M1.5 Iab-Ib), and alpha Herculis (Rasalgethi, M5 Ib-II). Spectral types come from the Bright Star Catalog. Although trigonometric parallaxes are listed in the catalog, they will not be very accurate for stars this far away. I derive photometric distances of around 400 light years for the first two and 600 light years for alpha Her. (Anybody have better sources, or do we have to wait for Hipparcos?) Anybody want to suggest more?
