The brightness of 4.2 mag, together with α2 (Secunda Giedo - 3.6 mag), forms an optical double star that can be distinguished with the naked eye under favorable conditions, in the northwest corner of the "triangular" constellation. The components are separated by 378 arcseconds, which corresponds to about 1/5 of the diameter of the full Moon. Prima Giedo is a giant star located 117 light-years away, while the supergiant Secunda Giedo is closer, at a distance of about 102 light-years. However, they form a beautiful pair of two orange-yellow stars in the sky. |
