NGC 4565 is a galaxy in the constellation Coma Berenices, lying between 30 and 50 million light-years from Earth. It is a class Sb spiral galaxy seen nearly edge on, as its plane is tipped only 4 degrees to our line of sight, displaying its large central bulge with yellow, old population II stars, peripheral spiral arms with young, hot blue, population I stars and its obscuring equatorial dust lane. NGC 4565 also marks our north galactic pole, much as Polaris marks the north celestial pole. Many background galaxies are visible, including a distant cluster of galaxies off the right hand tip of the galaxy/.
