2074 Shoemaker, provisional designation 1974 UA, is a stony Hungaria
Eugene Shoemaker.[2]
Orbit and classification
Shoemaker is a bright member of the dynamical
The body's observation arc begins with a precovery taken at Palomar in April 1954, more than 20 years prior to its official discovery observation.[4]
Physical characteristics
In the
SMASS classification, Shoemaker is a Sa-subtype, that transitions form the common stony S-type asteroids to the A-type asteroids.[1]
Rotation period
Several rotational
Suspected binary
In October 2003, photometric observations of Shoemaker by
719) in 2015, did not mention any mutual events.[9]
In June 2017, Warner measured a rotation period of 2.5331±0.0002 hours and an orbital period for the secondary of 44.28 hours at his CS3-Palmer Divide Station in California.[a][b] The binary nature of Shoemaker remains unconfirmed.
Diameter and albedo
According to the survey carried out by the
albedo between 0.41 and 0.52, respectively.[5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 4.93 kilometers based on an absolute magnitude of 13.9.[3]
Naming

The naming was also proposed by
