1067 Lunaria, provisional designation 1926 RG, is a stony Itha asteroid from the outer regions of the asteroid belt, approximately 18 kilometers in diameter. It was discovered on 9 September 1926, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany.[13] The asteroid was named after the flowering plant Lunaria (honesty).[2]
Orbit and classification
Lunaria is a member of the Itha family,[4] a very small family of asteroids, named after its parent body 918 Itha.[14]:23
It orbits the Sun in the outer asteroid belt at a distance of 2.3–3.4 AU once every 4 years and 10 months (1,777 days; semi-major axis of 2.87 AU). Its orbit has an eccentricity of 0.19 and an inclination of 11° with respect to the ecliptic.[1] The body's observation arc begins at Heidelberg in October 1926, one month after its official discovery observation.[13]
Physical characteristics
Lunaria has been characterized as both L- and S-type asteroid by Pan-STARRS photometric survey.[12] The overall spectral type for the Itha family is that of a stony S-type.[14]:23
Rotation period
In July 1984, a first rotational lightcurve of Lunaria was obtained by American astronomer Richard Binzel. Lightcurve analysis gave a rotation period of 7.74 hours with a brightness variation of 0.13 magnitude ({{{1}}}).[11] In September 2004, Donald Pray at the Carbuncle Hill Observatory (I00) derived a refined period of 6.057 hours with an amplitude of 0.27 magnitude from photometric observations ({{{1}}}).[10]
Diameter and albedo
According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Lunaria measures between 15.43 and 22.968 kilometers in diameter and its surface has an albedo between 0.1240 and 0.298.[6][7][8][9]
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 18.07 kilometers based on an absolute magnitude of 11.08.[3]
Naming
This minor planet was named after Lunaria (commonly known as "honesty"), a flowering plant in the mustard family. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 101).[2]
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 exclusively named after plants, in particular flowering plants (also see list of minor planets named after animals and plants).[15]
