396 Aeolia
Main-belt asteroid
From Wikipedia, the free encyclopedia
396 Aeolia is a typical main belt asteroid. It was discovered by the French astronomer Auguste Charlois on 1 December 1894 from Nice, and may have been named for the ancient land of Aeolis.[5] The asteroid is orbiting the Sun at a distance of 2.74 AU with a period of 4.54 years and an eccentricity (ovalness) of 0.16. The orbital plane is inclined at an angle of 2.5° to the plane of the ecliptic.[3] This is the largest member of the eponymously named Aeolia asteroid family, a small group of asteroids with similar orbits that have an estimated age of less than 100 million years.[6]

Analysis of the asteroid light curve based on photometry data collected during 2016 show a rotation period of 14.353±0.001 h with a brightness variation of 0.36±0.02 in magnitude. This rules out a previous estimate of 22.2 hours.[4] It is a metallic Xe type asteroid in the SMASS classification.[6]
