with a brightness of 4.2mag, it is, together with α2 (Secunda Giedo - 3.6mag), an optical binary, in favourable conditions distinguishable with the naked eye, at the northwest corner of the "triangular" constellation. In fact, the components lie 378 arc seconds apart, which is about 1/5 the diameter of the full Moon. Prima Giedo is the giant 117 light years away, while the giant Secunda Giedo lies closer, at a distance of about 102 light years. However, they are a pretty pair of two orange-yellow stars in the sky.
