152 Atala in the context of François-René de Chateaubriand

⭐ Core Definition: 152 Atala

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. The Henry brothers also named the last of their discoveries, 186 Celuta, after another Chateaubriand heroine. Both Atala and Céluta are American Indian fictional characters.

152 Atala in the context of D-type asteroid

D-type asteroids have a very low albedo and a featureless reddish spectrum. It has been suggested that they have a composition of organic-rich silicates, carbon and anhydrous silicates, possibly with water ice in their interiors. D-type asteroids are found in the outer asteroid belt and beyond; examples are 152 Atala, 944 Hidalgo and most Jupiter trojans. It has been suggested that the Tagish Lake meteorite was a fragment from a D-type asteroid, and that the Martian moon Phobos is closely related.

The Nice model suggests that D-type asteroids may have originated in the Kuiper belt. 46 D-type asteroids are known, including: 3552 Don Quixote, 944 Hidalgo, 624 Hektor, and 10199 Chariklo.
