798 Ruth is a minor planet orbiting the Sun that was discovered by the German astronomer Max Wolf on 21 November 1914. It may have been named after the biblical character Ruth. This main belt asteroid has an orbital period of 5.23 years and is orbiting at a distance of 3.0 AU from the Sun with an eccentricity (ovalness) of 0.036. The orbital plane is tilted by 9.2° from the plane of the ecliptic.
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. It is an M-type (metallic) asteroid that displays a significant component of the mineral olivine in its spectrum. 798 Ruth spans 43.19±2.9 km and rotates on its axis once every 8.55 h.
