Шаблон:Infobox planet

1195 Orangia, provisional designation Шаблон:Mp, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 24 May 1931, by South African astronomer Cyril Jackson at the Union Observatory in Johannesburg, South Africa.[1] It was named after the Orange Free State Province.[2]

Orbit and classification

Orangia is a member of the Flora family, one of the largest families of stony asteroids. It orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 5 months (1,239 days). Its orbit has an eccentricity of 0.20 and an inclination of 7° with respect to the ecliptic.[3] The asteroid's observation arc begins at Johannesburg, two weeks after its official discovery observation.[1]

Physical characteristics

Lightcurve

In November 2010, a rotational lightcurve of Orangia was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 6.167 hours with a brightness amplitude of 0.20 magnitude (Шаблон:Small).[4]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Orangia measures 6.258 kilometers in diameter and its surface has an albedo of 0.237,[5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of the Flora family – and calculates a diameter of 5.90 kilometers using an absolute magnitude of 13.31.[6]

Naming

This minor planet was named in honor of former South African Orange Free State Province that existed from 1910 to 1994.[2] The official naming citation was also mentioned in Paul Herget's The Names of the Minor Planets in 1955 (Шаблон:Small).[2]
