152 Atala is a large main belt asteroid that was discovered by brothers Paul Henry and Prosper Henry on 2 November 1875, but the discovery was credited to Paul. It is a type D asteroid, meaning that it is composed of carbon, organic rich silicates and possibly water ice.

The asteroid is named for the eponymous heroine of the 1801 novella Atala by François-René de Chateaubriand.^[8] The Henry brothers also named the last of their discoveries, 186 Celuta, after another Chateaubriand heroine.^[9] Both Atala and Céluta are American Indian fictional characters.^[10]

An occultation of a star by Atala was observed from Japan on 11 March 1994. Subsequent occultations have been observed as recently as 2006.^{[citation needed]}

Photometric of this asteroid made in 1981 gave a light curve with a period of 5.282 ± 0.004 hours with a brightness variation of 0.50 in magnitude.^[11]
