1230 Riceia, provisional designation 1931 TX1, is a stony background asteroid from the central regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 9 October 1931, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory.[8] The asteroid was named after Hugh Rice, amateur astronomer of New York and director of the Museum of Natural Sciences.[2]

Orbit and classification

[edit]

Riceia is a non-family asteroid from the main belt's background population.[4] It orbits the Sun in the central asteroid belt at a distance of 2.1–3.0 AU once every 4 years and 1 month (1,507 days; semi-major axis of 2.57 AU). Its orbit has an eccentricity of 0.18 and an inclination of 11° with respect to the ecliptic.[1]

The body's observation arc begins at Heidelberg on 17 October 1931, or eight days after its official discovery observation.[8]

Physical characteristics

[edit]

Riceia has been characterized as a stony S-type asteroid by Pan-STARRS photometric survey.[7]

Rotation period and pole

[edit]

In 2016, a rotational lightcurve of Riceia was modeled from photometric data from the Lowell Photometric Database. Lightcurve analysis gave a sidereal rotation period of 6.67317 hours as well as a spin axis of (37.0°, −63.0°) in ecliptic coordinates (λ, β).[6]

Diameter and albedo

[edit]

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Riceia measures 6.19 kilometers in diameter and its surface has a high albedo of 0.318.[5] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 7.46 kilometers based on an absolute magnitude of 13.0.[3]

Naming

[edit]

This minor planet was named after American amateur astronomer Hugh Rice, director of the Museum of Natural Sciences (possibly AMNH).[2] The naming was proposed by Irving Meyer and endorsed by German astronomer Gustav Stracke who mentioned on a postcard in February 1937, that his American college, Meyer, who himself did not discover any asteroids, requested the naming after the city of Rutherford, where a private observatory was located at the time.[9]

The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 113).[2]
