688 Melanie (rotation period of 18.9 hours and measures approximately 42 kilometers (26 miles) in diameter. Any reference to the origin of the asteroid's name is unknown.[2]
Orbit and classification
Melanie is a non-
semi-major axis of 2.7 AU). Its orbit has an eccentricity of 0.14 and an inclination of 10° with respect to the ecliptic.[3] The body's observation arc begins at Vienna Observatory in July 1913, or four years after its official discovery observation.[1]
Naming
This minor planet was named in 1910, by Otto Prelinger who collaborated with Johann Palisa and Max Wolf on the photographic star charts (AN 186, 15). Any reference of this minor planet's name to a person or occurrence is unknown.[2]

Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
The Collaborative Asteroid Lightcurve Link adopts the albedo obtained by IRAS and derives a diameter of 41.38 kilometers using an
asteroid occultation gave a best-fit ellipse dimension of (41.0 km × 41.0 km) with a low quality rating of 0.[6] These timed observations are taken when the asteroid passes in front of a distant star.[6]
