Its presence was first recorded by Abd al-Rahman al-Sufi in 964 CE, and this object is classified as a SA(s)b type under the de Vacouleurs-Sandage extended classification system. It is believed to have been formed when a metal-rich halo captured its first protogalatic fragments. Known to harbor two dense compact star clusters at its center, the dimmer one is believed to contain a supermassive black hole. Approaching our galaxy at about 300 kilometers per second, a collision with it is predicted to occur in about 2.5 billion years. For 10 points, name this spiral galaxy, the largest in the Local Group and the nearest to our own, named after a Greek mythological princess.
