1080 Orchis, provisional designation 1927 QB, is an dark background asteroid from the inner regions of the asteroid belt. It was discovered on 30 August 1927, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany. The carbonaceous F-type asteroid has a rotation period of 16.1 hours and measures approximately 22 kilometers (14 miles) in diameter. It was named after the flowering plant Orchis.
Orchis is a non-family asteroid of the main belt’s background population. It orbits the Sun in the inner asteroid belt at a distance of 1.8–3.0 AU once every 3 years and 9 months (1,374 days; semi-major axis of 2.42 AU). Its orbit has an eccentricity of 0.26 and an inclination of 5° with respect to the ecliptic. The asteroid was first observed as A906 BH at Heidelberg in January 1906. The body’s observation arc begins with its official discovery observation in August 1927.
This minor planet was named after the flowering plant Orchis, a genus in the orchid family. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 102).
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).
