1347 Patria, provisional designation1931 VW, is a carbonaceousasteroid from thebackground population of the centralasteroid belt, approximately 32 kilometers in diameter. It was discovered on 6 November 1931, by Soviet astronomerGrigory Neujmin at theSimeiz Observatory on the Crimean peninsula.[14] The asteroid was named for the Latin word offatherland.[3]
Patria is a non-family asteroid of the main belt'sbackground population.[5] It orbits the Sun in thecentral main-belt at a distance of 2.4–2.7 AU once every 4 years and 1 month (1,506 days;semi-major axis of 2.57 AU). Its orbit has aneccentricity of 0.07 and aninclination of 12° with respect to theecliptic.[1]
The asteroid was first identified asA898 VB atHeidelberg Observatory in November 1898. The body'sobservation arc begins a few days later atVienna Observatory, almost 33 years prior to its official discovery observation at Simeiz.[14]
Patria is an assumedC-type asteroid.[4]
In October 2005, a first rotationallightcurve ofPatria was obtained from photometric observations by French amateur astronomerLaurent Bernasconi. Lightcurve analysis gave a slightly longer-than averagerotation period of 29.5 hours with a brightness amplitude of 0.12magnitude (U=2).[12]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Patria measures between 30.72 and 34.98 kilometers in diameter and its surface has analbedo between 0.03 and 0.0462.[6][7][8][9][10][11]
TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.0506 and a diameter of 32.48 kilometers based on anabsolute magnitude of 11.3.[4]
Thisminor planet was named after "Patria", the Latin word for native country orfatherland. The official naming citation was mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 122).[3]
