Main-belt asteroid
369 Aëria provisional designation1893 AE , is a metallicasteroid and the parent body of theAeria family . It orbits in the central region of theasteroid belt , rotates every 4.778 hours and measures approximately 65 kilometers in diameter. The asteroid was discovered on 4 July 1893, by French astronomerAlphonse Borrelly at theMarseille Observatory in southeastern France.[ 18] Air ", one of the fourclassical elements : earth, water, air and fire.[ 2]
Orbit and classification [ edit ] Aëria is the parent body of theAeria family (539 [ 3] asteroid family of less than 300 known members,[ 19] : 23 Eunomia family (502 [ 4] 1184 Gaea ,3324 Avsyuk ,130066 Timhaltigin and144303 Mirellabreschi .[ 3]
Aëria orbits the Sun in thecentral main-belt at a distance of 2.4–2.9 AU once every 4 years and 4 months (1,577 days). Its orbit has aneccentricity of 0.10 and aninclination of 13° with respect to theecliptic .[ 1] observation arc begins at Marseille on 6 July 1893, two nights after its official discovery observation.[ 18]
Physical characteristics [ edit ] In theTholen classification ,Aëria is a metallicM-type asteroid .[ 1] [ 4] [ 16] [ 13] X-type , assigned to members of theAeria family .[ 19] : 23
Several rotationallightcurves ofAëria have been obtained from photometric observations since 1984, when it was first observed at ESO'sLa Silla Observatory in Chile. Lightcurve analysis gave a consolidatedrotation period of 4.778 hours with a brightness amplitude between 0.04 and 0.13magnitude (U=2/2/3/2/1 [ 10] [ 11] [ 12] [ 13] [ 14] [ 15]
Diameter and albedo [ edit ] According to the surveys carried out by the Infrared Astronomical SatelliteIRAS , the JapaneseAkari satellite and theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer ,Aëria measures between 60.00 and 73.77 kilometers in diameter and its surface has analbedo between 0.127 and 0.1919.[ 5] [ 6] [ 7] [ 8]
TheCollaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1919 and a diameter of 60.0 kilometers based on anabsolute magnitude of 8.52.[ 5] [ 4]
Aëria has been observed by astronomers during at least two occultation events: the first in December 2015 and the other in February 2018.[ 20]
Thisminor planet was named after "Air ", one of the fourclassical elements : earth, water, air and fire. It is thought that the asteroid's name may have also been inspired by the two letters of its provisional designation,1893 AE .[ 2]
