1291 Phryne , provisional designation 1933 RA , is an Eoan asteroid from the outer regions of the asteroid belt , approximately 27 kilometers in diameter. It was discovered on 15 September 1933, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle.[13] Phryne .
Orbit and classification [ edit ]
Phryne is a member the Eos family (606 [4] asteroid family in the outer main belt consisting of nearly 10,000 asteroids.[14] : 23 AU eccentricity of 0.09 and an inclination of 9° with respect to the ecliptic .[1] observation arc begins with its first identification as A907 TA at Heidelberg Observatory in October 1907.[13]
Physical characteristics [ edit ]
Phryne is an assumed stony S-type asteroid ,[3] spectral type is that of a K-type .[14] : 23
Rotation period [ edit ]
In May 1984, a rotational lightcurve of Phryne was obtained by astronomer Richard Binzel . Lightcurve analysis gave a well-defined rotation period of 5.55 hours with a brightness variation of 0.86 magnitude (U=3 [9] Pierre Antonini gave a period of 5.58410 hours and an amplitude of 0.38 magnitude (U=3 [10]
In 2011, a modeled lightcurve using data from the Uppsala Asteroid Photometric Catalogue (UAPC) and other sources gave a period 5.58414 hours, as well as two spin axis of (106.0°, 35.0°) and (277.0°, 59.0°) in ecliptic coordinates (λ, β).[12] [11]
Diameter and albedo [ edit ]
According to the surveys carried out by the Infrared Astronomical Satellite IRAS , the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , Phryne measures between 24.954 and 31.13 kilometers in diameter and its surface has an albedo between 0.127 and 0.1818.[5] [6] [7] [8]
The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1355 and a diameter of 26.52 kilometers based on an absolute magnitude of 10.67.[3]
This minor planet was named after Phryne , the beautiful ancient Greek courtesan (hetaira ) of the 4th century B.C. Supposedly, she was the model for the statue Aphrodite of Knidos by ancient Greek sculptor Praxiteles (see asteroid 5983 ) , who was also her lover. It was the first nude statue of a woman from ancient Greece. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 118 [2]
