369 Aëria is a large asteroid residing in the asteroid belt that was discovered by the French astronomer A. Borrelly on July 4, 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. The period estimate has since been refined, giving a value of 4.7781 hours.
