1099 Figneria , provisional designation 1928 RQ , is an asteroid from the background population of the outer regions of the asteroid belt , approximately 26 kilometers in diameter. Discovered by Grigory Neujmin at Simeiz Observatory in 1928, the asteroid was later named after Russian revolutionary activist Vera Figner .[12]
Discovery
[ edit ]
Figneria was discovered by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula on 13 September 1928.[12] On the same night, it was independently discovered by German astronomer Max Wolf at the Heidelberg Observatory in southwest Germany.[2] [a] The Minor Planet Center , however, only acknowledges the first discoverer.[12]
In October 1927, the asteroid was first identified as A917 UF at Simeiz, where the body's observation arc begins 11 months later with its official discovery observation.[12]
Orbit and classification
[ edit ]
Figneria is a non-family asteroid of the main belt's background population . It orbits the Sun in the outer main belt at a distance of 2.3–4.1 AU once every 5 years and 8 months (2,071 days). Its orbit has an eccentricity of 0.28 and an inclination of 12° with respect to the ecliptic .[1]
Physical characteristics
[ edit ]
PanSTARRS photometric survey gave Figneria a spectral type of an L- and S-type asteroid ,[10] while it has been characterized as a K-type asteroid based on polarimetric observations.[11] The asteroid is also an assumed carbonaceous C-type asteroid .[3]
Rotation period
[ edit ]
In September 2007, a rotational lightcurve of Figneria was obtained by astronomer Julian Oey at the Kingsgrove (E19 ) and Leura Observatories (E17 ) in Australia. Lightcurve analysis gave a rotation period of 13.577 hours with a brightness variation of 0.16 magnitude (U=3- ).[8] In January 2014, photometric observations at the Palomar Transient Factory in California gave a period of 13.583 hours and an amplitude of 0.15 magnitude (U=2 ).[9]
Diameter and albedo
[ edit ]
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 , Figneria measures between 23.309 and 29.39 kilometers in diameter and its surface has an albedo between 0.1415 and 0.225.[4] [5] [6] [7]
The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1683 and a diameter of 29.55 kilometers based on an absolute magnitude of 10.2.[3]
Naming
[ edit ]
This minor planet was named by the discoverer after Vera Figner (1852–1942), a Russian writer and revolutionary political activist. The official naming citation was published in the Planetenzirkular des Astronomischen Rechen-Institut (RI 789 ).[2]
