293 Brasilia
Brasilia (minor planet designation: 293 Brasilia) is a large Main belt asteroid that was discovered by French astronomer Auguste Charlois on 20 May 1890 in Nice. It is the namesake of the Brasilia family, a smaller asteroid family of X-type asteroids in the outer main-belt. However, Brasilia is a suspected interloper in its own family.: 23
