Albireo is a star in the constellation Cygnus, and although at first glance looks like a single star, when you look with good binoculars or a telescope, you discover that is not a star, if not two. The brightest star is yellow (Albireo A), and the fainter, blue (Albireo B), offering an incredible contrast, one of the favorite double stars by amateur astronomers.

But it does not end there, as the brightest, Albireo A, is itself another double star, and which consists of two stars. But at that level of detail I could not get there, I could only see the top two, which I described earlier, and that can see in the picture that heads this post, a picture I made and did not go all wrong, where you can see the two stars and the size and color of each.

The magnitude of both stars are of 3.05 and 5.12 respectively. Remember, to a lesser extent, higher gloss. To give you an idea, the brightness of the moon when in the new moon phase is -12, and the brightest stars we see in the sky with the naked eye often have magnitudes between -1 and 2, and when Venus is visible, usually have a magnitude of about -3. In addition, the distance between Albireo and us is about 385 light years away (one light year equals about 9.46 × 10 12 km, so you can get an idea of \u200b\u200bhow "far away" that is). Lately I've been following

occasional double. If I have the opportunity to photograph them, set them here.
