159 Aemilia is a large Main belt asteroid. This slowly rotating, dark asteroid has a primitive carbonaceous composition.
It orbits within the Hygiea family, although it may be an unrelated interloping asteroid, as it is too big to have arisen from the cratering process that most likely produced that family.
Aemilia was discovered by the brothers Paul Henry and Prosper Henry on January 26, 1876. The credit for this discovery was given to Paul. It is probably named after the Via Aemilia, a Roman road in Italy that runs from Piacenza to Rimini.
Two stellar occultations by Aemilia have been recorded so far, the first in 2001 and the second in 2003 [link].
