337 Devosa

337 Devosa is a large Main belt asteroid. It was discovered by Auguste Charlois on 22 September 1892 in Nice. The asteroid is orbiting the Sun at a distance of 2.38 AU with a period of 3.68 years and an eccentricity (ovalness) of 0.14. These orbital elements are similar to that of the large asteroid 4 Vesta.^[3] The orbital plane of 337 Devosa is tilted at an angle of 7.85° to the plane of the ecliptic.^[1]
