1434 Margot, provisional designation 1936 FD1, is a stony Eoan asteroid from the outer regions of the asteroid belt, approximately 29 kilometers in diameter. It was discovered on 19 March 1936, by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula.[12] The asteroid was named after Gertrud Margot Görsdorf, a friend of German astronomer of Wilhelm Gliese.[2]
Margot is a member the Eos family (606),[3][4] the largest asteroid family of the outer asteroid belt consisting of nearly 10,000 asteroids.[13]: 23 It orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,916 days). Its orbit has an eccentricity of 0.07 and an inclination of 11° with respect to the ecliptic.[1]
The body's observation arc begins at Vienna Observatory in August 1906, when it was first identified as A922 SD, almost 30 years prior to its official discovery observation at Simeiz.[12]
In June 1984, a rotational lightcurveofMargot was obtained from photometric observations by American astronomer Richard Binzel . Lightcurve analysis gave a well-defined rotation period of 8.17 hours with a brightness amplitude of 0.52 magnitude, indicative of a somewhat elongated shape (U=3).[10]
This minor planet was named by German astronomer Wilhelm Gliese after Gertrud Margot Zottmann (1915–1990; née Görsdorf), his friend and schoolfellow for several years at Berlin. Gliese, after whom the asteroid (1823) is named, is best known for the Gliese Catalogue of Nearby Stars, which is itself the source of name for many discovered exoplanets.[2] The discovery circumstances and naming were researched by Lutz Schmadel, the author of the Dictionary of Minor Planet Names.[2]
