Orbit and classification

Stentor

[5]

[6]

It orbits the Sun at a distance of 4.7–5.7 AU once every 11 years and 10 months (4,327 days; semi-major axis of 5.2 AU). Its orbit has an eccentricity of 0.10 and an inclination of 39° with respect to the ecliptic. The body's observation arc begins with its official discovery observation at La Silla in October 1976.^[1]

Physical characteristics

Rotation period

In June 2016, a rotational lightcurve of Stentor was obtained from photometric observations by Brian Warner at the Center for Solar System Studies (CS3) in California. Lightcurve analysis gave a rotation period of {{val|16.40|0.02}} hours with a brightness amplitude of 0.10 magnitude ({{small|U=2}}). An alternative period solution (1:1.5 alias of 24.88 was also obtained.^[9]^[10]{{efn|name=lightcurve-plots-CS3}}

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Stentor measures 50.76 kilometers in diameter and its surface has an albedo 0.082,^[8] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 58.29 kilometers based on an absolute magnitude of 9.9.^[9]

Naming

This minor planet was named from Greek mythology after Stentor, the Greek warrior and herald with a voice as loud as fifty men together.^[1] The official naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 4788}}).^[32]

Its orbit has an eccentricity of 0.10 and an inclination of 39° with respect to the ecliptic.
