Edith is asteroid #517 and also known as 1903 MH. Edith is of the type X. Edith’s orbit is characterized by a semi-major axis of 3.16 Astronomical Units, an eccentricity of 0.18, a period of revolution of 2 049 days, and an inclination of 3.2 degrees. Edith was discovered by the American astronomer Raymond Smith Dugan at the Heidelberg-Königstuhl State Observatory (Landessternwarte Heidelberg-Königstuhl), where and while Raymond Smith Dugan made his Ph.D.

Edith is named after Edith Dugan Eveleth, the sister of the asteroid discoverer. She perhaps was counted in a census of 1940, but besides this, nothing is publicly known about her. The name Edith shall be the modern variant of the Old English name Ēadgȳþ, that is derived from the words for prosperity and for battle. A too strange name for deriving anything from it. The asteroid #517 represents a not further described sister or a sister without influence. Aspects with this asteroid to other asteroids named after members of the Dugan Family indicate certain types of relationship, so would an aspect between asteroid #503 (Evelyn) and asteroid #517 indicate a mother-daughter relationship.
