Binary star, with component magnitudes reaching values of 2.9 and 6.3, their separation is 2.4" and the distance from Earth is 124 light-years. It is a good test for a 10-15 cm telescope. The primary component is reported by observers as white, pale blue, or even blue-green, while the secondary appears pale blue to blue. |
