462 ERIPHYLA / ɛR ɪ ˈ F Aɪ L ə / ( Prov. Обозначение : A900 UJ или 1900 FQ ) - это коронский астероид из внешних областей астероидного пояса . Это было обнаружено немецким астрономом Максом Вольфом в государственной обсерватории Гейдельберг-Кёнигстухла 22 октября 1900 года. ^{[ 1 ]} Астероид каменного S-типа имеет период вращения 8,7 часа и имеет диаметр приблизительно 35 километров (22 мили). Он был назван в честь Эрифила , из греческой мифологии. ^{[ 3 ]}

Орбита и классификация

Эрифила является основным членом семьи Коронис ( 605 ), очень большой внешней семейства астероидов с почти коплярными эклиптическими орбитами. ^{[ 13 ]}^{[ 14 ]}^{[ 6 ]}^{[ 7 ]} Он вращает солнце во внешнем астероидном поясе на расстоянии 2,6–3,1 AU один раз каждые 4 года и 10 месяцев (1777 дней; Полу мажорная ось 2,87 AU). Его орбита имеет эксцентриситет 0,09 и наклон 3 ° по отношению к эклиптике . ^{[ 4 ]} Астероид впервые наблюдался как A896 YA в NICE Обсерваторию тела 31 декабря 1896 года. Наблюдательную дугу начинается в Гейдельберге 11 ноября 1900 года, через три недели после официального наблюдения за открытием. ^{[ 1 ]}

Naming

This minor planet was named from Greek mythology after Eriphyle, wife of Amphiaraus whom she persuaded to take part in a raiding venture which lead to the tragic war of the Seven against Thebes. The naming was also mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 50).^[3]

Physical characteristics

In both the Tholen and SMASS classification, Eriphyla is a common stony S-type asteroid.^[4]

Rotation period

In October 2002, a rotational lightcurve of Eriphyla was obtained from photometric observations by Stephen M. Slivan. Lightcurve analysis gave a well-defined rotation period of 8.659±0.001 hours with a brightness variation of 0.222±0.022 magnitude (U=3).^[12] Several more lightcurves were published since 1987.^[15]^[16]^[17]^[18]

A modeled lightcurve using photometric data from the Lowell Photometric Database and from the Wide-field Infrared Survey Explorer (WISE) was published in 2018. It gave a concurring sidereal period of 8.65890±0.00002 hours and includes two spin axes at (119.0°, 7.0°) and (301.0°, 5.0°) in ecliptic coordinates (λ, β).^[19]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, Eriphyla measures between 34.274 and 41.882 kilometers in diameter and its surface has an albedo between 0.1746 and 0.2829.^[6]^[8]^[10]^[11]^[13] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.2438 and derives a diameter of 35.32 kilometers based on an absolute magnitude of 9.41.^[13]
