1060 Magnolia , provisional designation 1925 PA , is a stony Florian
asteroid from the inner regions of the
asteroid belt , approximately 7 kilometers in diameter. It was discovered on 13 August 1925, by German astronomer
Karl Reinmuth at the
Heidelberg-Königstuhl State Observatory .
[18] The asteroid was named after the flowering plant
magnolia .
[3]
Orbit and classification
Magnolia is a member of the
Flora family (
402 ),
[4]
[5] a giant
asteroid family and the largest family of stony asteroids in the main-belt.
[19] : 23 It orbits the Sun in the
inner asteroid belt at a distance of 1.8–2.7
AU once every 3 years and 4 months (1,222 days;
semi-major axis of 2.24 AU). Its orbit has an
eccentricity of 0.20 and an
inclination of 6
° with respect to the
ecliptic .
[1]
The body's
observation arc begins at Heidelberg in September 1925, or one month after its official discovery observation.
[18]
Physical characteristics
Pan-STARRS ' photometric survey characterizes Magnolia as a common, stony
S-type asteroid ,
[17] which is also the overall
spectral type for members of the Flora family.
[19] : 23
Rotation period
Several rotational
lightcurves of Magnolia have been obtained from photometric observations since 1992.
[11]
[12]
[13]
[14]
[15]
[16] The best-rated lightcurve by French amateur astronomers Jacques Michelet and Maurice Audejean gave a relatively short
rotation period of 2.9107 hours with a brightness amplitude of 0.14
magnitude (
U=3 ).
[4]
[13]
Diameter and albedo
According to the survey carried out by the
NEOWISE mission of NASA's
Wide-field Infrared Survey Explorer (WISE), Magnolia measures between 5.23 and 9.65 kilometers in diameter and its surface has an
albedo between 0.173 and 0.47.
[6]
[7]
[8]
[9]
[10]
The Collaborative Asteroid Lightcurve Link adopts
Petr Pravec 's revised WISE results, that is, an albedo of 0.2839 and a diameter of 7.16 kilometers based on an
absolute magnitude of 12.71.
[4]
[9]
Naming
This
minor planet was named after a
genus of flowering plants,
magnolia , which was in turn named after
Pierre Magnol . The official naming citation was mentioned in
The Names of the Minor Planets by
Paul Herget in 1955 (
H 101 ).
[3]
Reinmuth's flowers
Due to his many discoveries,
Karl Reinmuth submitted a large list of 66 newly named asteroids in the early 1930s. The list covered his discoveries with numbers between
(1009) and
(1200) . This list also contained a sequence of 28 asteroids, starting with
1054 Forsytia , that were all named after plants, in particular
flowering plants (also see list of minor planets named after animals and plants) .
