LEDA 1245565 (known as RX J1140.1+0307) is a spiral galaxy located 1.04 billion light-years away in the constellation of Virgo. [1] It has a similar structure to the Milky Way, though it has a low black hole mass. [2] [3] [4] It has an active galactic nucleus [5] and is classified as a narrow-line Seyfert 1 galaxy [6] with enhanced star formations. [7]
