5542 Moffatt, provisional designation 1978 PT4, is a Marian
Ethelwin Moffatt, a benefactor of the discovering observatory.[1]
Orbit and classification
Moffatt is a core member of the
502), one of the most prominent families in the intermediate main belt with more than 5,000 members.[5]
It orbits the Sun in the
semi-major axis of 2.59 AU). Its orbit has an eccentricity of 0.16 and an inclination of 16° with respect to the ecliptic.[2] The body's observation arc begins with its first observation at Palomar Observatory in July 1978, a month prior to its official discovery observation at Bickley.[1]
Physical characteristics
Moffatt is an assumed stony S-type asteroid.[5]
Rotation period

Diameter and albedo
According to the survey carried out by the
albedo of 0.345.[6][7] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the parent body of the Eunomia family – and calculates a diameter of 10.06 kilometers based on an absolute magnitude of 12.3.[5]
