798 Ruth

Main-belt asteroid

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.[4] 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.[2]

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.[5] It is an M-type (metallic) asteroid that displays a significant component of the mineral olivine in its spectrum.[3] 798 Ruth spans 43.19±2.9 km and rotates on its axis once every 8.55 h.[2]
