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]

Discovery[edit]

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]

Orbit and classification[edit]

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]

Physical characteristics[edit]

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]

Rotation period and poles[edit]

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]

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, 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]

Naming[edit]

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.
