Discoverer P. P. Henry, 1875

152 Atala is a very large, dark main belt asteroid. It is a type D asteroid, meaning that it is composed of carbon, organic rich silicates and possibly water ice.

It was discovered by brothers Paul Henry and Prosper Henry on November 2, 1875, but the discovery was credited to Paul. It is named after Atala, eponymous heroine of the 1801 novel by François-René de Chateaubriand.

An occultation of a star by Atala was observed from Japan on March 11, 1994. Subsequent occultations have been observed as recently as 2006.
