798 Ruth is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on 21 November 1914. It was named after the biblical character Ruth.
This is a member of the dynamic Eos family of asteroids that most likely formed as the result of a collisional breakup of a parent body.[3]
