Main-belt asteroid
369 Aëria provisional designation 1893 AE , is a metallic asteroid and the parent body of the Aeria family . It orbits in the central region of the asteroid belt , rotates every 4.778 hours and measures approximately 65 kilometers in diameter. The asteroid was discovered on 4 July 1893, by French astronomer Alphonse Borrelly at the Marseille Observatory in southeastern France.[ 18] Air ", one of the four classical elements : earth, water, air and fire.[ 2]
Orbit and classification
Aëria is the parent body of the Aeria family (539 [ 3] asteroid family of less than 300 known members,[ 19] : 23 Eunomia family (502 [ 4] 1184 Gaea , 3324 Avsyuk , 130066 Timhaltigin and 144303 Mirellabreschi .[ 3]
Aëria orbits the Sun in the central main-belt at a distance of 2.4–2.9 AU once every 4 years and 4 months (1,577 days). Its orbit has an eccentricity of 0.10 and an inclination of 13° with respect to the ecliptic .[ 1] observation arc begins at Marseille on 6 July 1893, two nights after its official discovery observation.[ 18]
Physical characteristics
In the Tholen classification , Aëria is a metallic M-type asteroid .[ 1] [ 4] [ 16] [ 13] X-type , assigned to members of the Aeria family .[ 19] : 23
Rotation period
Several rotational lightcurves of Aëria have been obtained from photometric observations since 1984, when it was first observed at ESO's La Silla Observatory in Chile. Lightcurve analysis gave a consolidated rotation period of 4.778 hours with a brightness amplitude between 0.04 and 0.13 magnitude (U=2/2/3/2/1 [ 10] [ 11] [ 12] [ 13] [ 14] [ 15]
Diameter and albedo
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 , Aëria measures between 60.00 and 73.77 kilometers in diameter and its surface has an albedo between 0.127 and 0.1919.[ 5] [ 6] [ 7] [ 8]
The Collaborative 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 an absolute magnitude of 8.52.[ 5] [ 4]
Occultation events
Aëria has been observed by astronomers during at least two occultation events: the first in December 2015 and the other in February 2018.[ 20]
Naming
This minor planet was named after "Air ", one of the four classical 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]
