(wife of Heinrich Vogt) Eos
1410 Margret, provisional designation , is an Eoan asteroid from the outer regions of the asteroid belt, approximately 21 kilometers in diameter. It was discovered on 8 January 1937, by astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany. The asteroid was named after Margret Braun, wife of the Heidelberg astronomer Heinrich Vogt.
Orbit and classification
Margret is a member of the Eos family (606), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids.
It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,917 days). Its orbit has an eccentricity of 0.11 and an inclination of 10° with respect to the ecliptic.
The body's observation arc begins with its first identification as at Simeiz Observatory in September 1924, more than 12 years prior to its official discovery observation at Heidelberg.
Physical characteristics
The asteroid's spectral type is unknown. The Eos family typically consists of K-type asteroids.
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Margret measures 21.083 kilometers in diameter and its surface has an albedo of 0.145, which agrees with the albedo of 0.14 measured for the parent body of the Eos family, 221 Eos.
Rotation period
As of 2017, no rotational lightcurve of Margret has been obtained from photometric observations. The asteroid's rotation period, spin axis and shape remain unknown.
Naming
This minor planet was named after Margret Braun (died 1991), wife of the Heidelberg astronomer Heinrich Vogt (1890–1968), after whom was named. The subsequently numbered asteroid is also named after Margret Braun. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 127).
