    1072 Malva, provisional designation 1926 TA, is a dark background asteroid from the outer regions of the asteroid belt, approximately 48 kilometers in diameter. It was discovered on 4 October 1926, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in Germany. [12] The asteroid was named after the flowering plant Malva (mallow). [3]

    Orbit and classification

    Malva is a non-family asteroid from the main belt's background population. [5] It orbits the Sun in the outer asteroid belt at a distance of 2.4–3.9  AU once every 5 years and 8 months (2,057 days; semi-major axis of 3.17 AU). Its orbit has an eccentricity of 0.24 and an inclination of 8° with respect to the ecliptic. [1] The body's observation arc begins with its official discovery observation at Heidelberg in October 1926. [12]

    Physical characteristics

    Malva is an assumed C-type asteroid. [4]

    Rotation period

    Observations performed by Brian Warner at the Palmer Divide Observatory in Colorado Springs, Colorado, during 2007 produced a lightcurve with a period of 10.080 ± 0.005 hours and a brightness range of 0.17 ± 0.02 in magnitude ( U=3 ). [11] [lower-alpha 1] Another lightcurve obtained by Italian amateur astronomers Roberto Crippa and Federico Manzini at the Sozzago Astronomical Station ( A12 ) gave a period of 9.0127 hours with an amplitude of 0.17 magnitude ( U=2 ). [10]

    Diameter and albedo

    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, Malva measures between 45.05 and 53.675 kilometers in diameter and its surface has an albedo between 0.032 and 0.0549. [6] [7] [8] [9]

    The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0458 and a diameter of 44.97 kilometers based on an absolute magnitude of 10.7. [4]

    Naming

    This minor planet was named after the genus of flowering plants, Malva , also known as mallow. 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), and 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). [13]
