NGC 3613 is a barred spiral galaxy located approximately 55 million light-years away in the constellation Leo. It was discovered by the astronomer William Herschel in 1784 and is notable for its bright core and well-defined spiral arms. The galaxy has an apparent magnitude of about 11.5, making it faintly visible through small telescopes. NGC 3613 is part of the Virgo Supercluster and is often studied for its structure and star formation activities, contributing to our understanding of galaxy evolution.
