Capella is the brightest star in the constellation Auriga and one of the brightest stars in the night sky. It's actually a system of four stars in two binary pairs! Think of it like a celebrity couple and their equally famous siblings. Its yellowish color resembles our Sun, though it's much older. Imagine Capella as the "sun" of another planetary system, just shining a bit differently. It is easily visible even in urban areas if the skies are clear enough.
