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]
