Delia (minor planet designation: 395 Delia) is a large Main belt asteroid. It was discovered by the French astronomer Auguste Charlois on 30 November 1894 in Nice. Delia is an alternate name for the ancient Greco-Roman Moon goddess.[4] This asteroid is orbiting the Sun at a distance of 2.79 AU with an orbital eccentricity (ovalness) of 0.085 and a period of 4.64 yr. The orbital plane is tilted at an angle of 3.35° to the plane of the ecliptic.[2]

This is a dark, carbonaceous body with a low albedo of 0.03 and is classified as a C-type asteroid in the Tholen taxonomy. It has an estimated cross-section of 44.2[2] km/s and is spinning with a rotation period of 19.7 hours.[3]
