855 Newcombia (

rotation period of 3.0 hours and measures approximately 12 kilometers (7.5 miles) in diameter. It was named after Canadian–American astronomer Simon Newcomb (1835–1909).[2]

Orbit and classification

Newcombia is a non-

semi-major axis of 2.36 AU). Its orbit has an eccentricity of 0.18 and an inclination of 11° with respect to the ecliptic.[3]

Discovery

Newcombia was discovered by Soviet-Russian astronomer

Heidelberg Observatory on 28 April 2016.[2] The Minor Planet Center, however, only credits the first discoverer.[1]

Naming

This

Newcomb were also named in his honor.[12][13]

Physical characteristics

In the SDSS-based taxonomy, Newcombia is a common, stony S-type asteroid.[11]

Rotation period

In October 2004, a rotational

U=3).[10][14]

An identical period of 3.003±0.001 hours with an amplitude of 0.33±0.02 magnitude was determined in April 2014, by

U=3/3).[17][a]

Diameter and albedo

According to the surveys carried out by the Japanese

albedo of (0.285±0.017) and (0.219±0.040), respectively.[6][7][8] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a stony asteroid of 0.20 and calculates a diameter of 13.58 kilometers based on an absolute magnitude of 11.7.[14] Alternative mean-diameter measurements published by the WISE team include (10.19±1.49 km) and (12.930±0.133 km) with corresponding albedos of (0.41±0.19) and (0.2037±0.0483).[5][14]
