369 Aëria is a large asteroid residing in the asteroid belt that was discovered by the French astronomer A. Borrelly on 4 July 1893 in Marseilles. Based upon the spectrum, it is classified as an M-type asteroid.
In 1984, the asteroid was observed from the European Southern Observatory, allowing a composite light curve to be produced. This asymmetric curve showed a rotation period of 4.787 ± 0.005 hours and a low brightness variation of 0.08 ± 0.01 in magnitude.[2] The period estimate has since been refined, giving a value of 4.7781 hours.[1]
