1350 Rosselia, provisional designation 1934 TA, is a stony Koronian asteroid from the outer regions of the asteroid belt, approximately 22 kilometers in diameter. Discovered by astronomer Eugène Delporte at the Royal Observatory of Belgium in 1934, [17] the asteroid was later named after Marie-Thérèse Rossel, editor of the Belgian newspaper Le Soir. [2]
Rosselia was discovered on 3 October 1934, by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle. [17] One month later, it was independently discovered by German astronomer Richard Schorr at the Bergedorf Observatory, Hamburg, on 3 November 1934. [2] The Minor Planet Center only recognizes the first discoverer. The asteroid was first identified as A924 TB at the Simeiz Observatory in October 1924. [17]
Rosselia is a member of the Koronis family ( 605), [3] [4] a very large asteroid family with nearly co-planar ecliptical orbits in the outer main belt. [18] It orbits the Sun at a distance of 2.6–3.1 AU once every 4 years and 10 months (1,764 days; semi-major axis of 2.86 AU). Its orbit has an eccentricity of 0.09 and an inclination of 3 ° with respect to the ecliptic. [1]
The body's observation arc begins at Lowell Observatory in September 1929, or five years prior to its official discovery observation at Uccle. [17]
In the Tholen classification, Rosselia is a common S-type asteroid. [1] In the SMASS classification it is an Sa-subtype that transitions to the rare A-type asteroids. [1]
Several rotational lightcurve of Rosselia have been obtained from photometric observations since 1975. [10] [11] [12] [15] Consolidated lightcurve-analysis gave a well-defined rotation period of 8.140 hours with a brightness amplitude between 0.3 and 0.54 magnitude ( U=3). [3]
Modeling of the asteroid's lightcurve gave two concurring periods of 8.14008 and 8.14011 hours, [13] [14] with two determined spin axis of (67.0°, −64.0°) and (246.0°, −58.0°) in ecliptic coordinates (λ, β). [13]
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, Rosselia measures between 20.822 and 23.35 kilometers in diameter and its surface has an albedo between 0.1579 and 0.199. [5] [6] [7] [8] [9]
The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1579 and a diameter of 23.35 kilometers based on an absolute magnitude of 10.78. [3] [9]
This minor planet was named after Marie-Thérèse Rossel (1910–1987), a Belgian businesswoman and editor of the Brussels newspaper Le Soir. [2] The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ( H 122). [2] Asteroid 1366 Piccolo was also named after an editor of Le Soir by Delporte.
