718 Erida
718 Erida is a minor planet orbiting the Sun. It was discovered at Vienna on September 29, 1911, by Austrian astronomer Johann Palisa,[2] and was named for Erida Leuschner, daughter of astronomer Armin Otto Leuschner.[3] It is orbiting at a distance of 3.06 AU with a period of 5.34 yr and an eccentricity of 0.20. The orbital plane of this asteroid is inclined by an angle of 6.9° to the plane of the ecliptic.[1]
Photometric observations made during 2009 were used to produce a light curve for this asteroid that showed a rotation period of 17.447±0.002 h with a brightness variation of 0.37 in magnitude.[4] It spans a girth of approximately 72 km.[1]
