293 Brasilia is a largeMain beltasteroid that was discovered by French astronomerAuguste Charlois on 20 May 1890 inNice. It is the namesake of theBrasilia family, a smallerasteroid family ofX-type asteroids in theouter main-belt. However,Brasilia is a suspectedinterloper in its own family.[1]: 23
Photometric observations of this asteroid at the Leura Observatory inLeura, Australia during 2006 gave alight curve with a period of 8.173 ± 0.002 hours and a brightness variation of 0.20 ± 0.03 inmagnitude.[3]
