Characteristics:
NGC 4565 is an edge-on spriral galaxy about 30 to 50 million Lj away in the constellation Coma Berencices. The 10th magnitude galaxy sits perpendicular to our own Milky Way galaxy and is almost directly above the North Galactic Pole (in the same way Polaris is located above the Earth's North Pole).
It is known as the Needle Galaxy for its narrow profile. First spotted in 1785 by Sir William Herschel (1738–1822), this is one of the most famous examples of an edge-on spiral galaxy. "Visible through a small telescope, some sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed."
NGC 4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy and it has been proposed that if it were viewed face-on, it would be the most spectacular of the galaxies of its type in the nearby Universe.

Much speculation exists in the literature as to the nature of the central bulge. In the absence of clear-cut dynamical data on the motions of stars in the bulge, the photometric data alone cannot adjudge among various options put forth. However, its exponential shape suggested that it is a barred spiral galaxy. Subsequent studies with the help of the Spitzer Space Telescope not only confirmed the presence of a central bar but also showed a pseudobulge within it as well as an inner ring.

NGC 4565 has at least two companion galaxies, one of which is interacting with it. The galaxie left/under NGC4565 seen on the image above, is NGC4562, one of the two compagnion.
NGC 4565 has a population of roughly 240 globular clusters, more than the Milky Way. (
