1111 Reinmuthia (
rotation period of 4.02 hours and measures approximately 40 kilometers (25 miles) in diameter.[7] It was later named in honor of Karl Reinmuth, the discoverer himself.[2]
Orbit and classification
Reinmuthia is a non-
semi-major axis of 2.99 AU). Its orbit has an eccentricity of 0.10 and an inclination of 4° with respect to the ecliptic.[1] The body's observation arc begins at Heidelberg with its official discovery observation.[3]

Physical characteristics
Lightcurve
-based 3D inversion model of ReinmuthiaIn the
spectral type, closest to that of a dark F-type and somewhat similar to an X-type asteroid. The spectrum had also been flagged as "unusual" and "nosy" by Tholen (FXU:).[1]

Poles and shape
Lightcurve inversion also modeled the body's shape and
US Naval Observatory, the Uppsala Asteroid Photometric Catalogue, the Palomar Transient Factory and the Catalina Sky Survey gave a similar sidereal period of 4.007347 hours and two spin axes of (356.0°, 68.0°) and (153.0°, 78.0°) in ecliptic coordinates (λ, β). The body's very elongated shape had already been indicated by the high brightness variation measured during the photometric observations.[9]
Diameter and albedo
According to the survey carried out by the Japanese
albedo of 0.167.[6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and derives a diameter of 41.26 kilometers based on an absolute magnitude of 10.65.[7]
