3255 Tholen, provisional designation 1980 RA, is a stony

rotation period of 2.95 hours.[4] It was later named after American astronomer David Tholen.[2]

Orbit and classification

Tholen is a

semi-major axis of 2.37 AU). Its orbit has an eccentricity of 0.36 and an inclination of 21° with respect to the ecliptic.[3] In September 1969, it was first observed as 1969 SD at the Argentinian El Leoncito site, extending the body's observation arc by 11 years prior to its official discovery observation at Anderson Mesa.[1]

Naming

M.P.C. 11749).[10]

Physical characteristics

In the

Bus–DeMeo classification, Tholen is a common S-type asteroid.[3][9]

Diameter and albedo

According to the space-based survey carried out by the Japanese

albedo of 0.14 and 0.34, respectively,[5][6][7][8] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 5.1 kilometers with an absolute magnitude of 13.84.[4]

Rotation period

Several rotational

lightcurves were obtained for this asteroid from photometric
observations.

In September 2013, Italian astronomer Andrea Ferrero at the Bigmuskie Observatory (

U=3-/3-).[a]

The results supersede two older lightcurves from 1991 and 2002, that gave a period of 3±1 and 6 hours, respectively (

U=1/1).[12][13]
