1042 Amazone, provisional designation1925 HA, is a darkasteroid andslow rotator in the outerasteroid belt, approximately 70 kilometers in diameter. It was discovered on 22 April 1925, by German astronomerKarl Reinmuth atHeidelberg Observatory in southern Germany.[1] It is named after theAmazons from Greek mythology.[2]
Amazone orbits the Sun in theouter main-belt at a distance of 3.0–3.5 AU once every 5 years and 10 months (2,131 days). Its orbit has aneccentricity of 0.09 and aninclination of 21° with respect to theecliptic.[1] The body'sobservation arc begins three weeks after its official discovery observation.[11]
Thecarbonaceous asteroid has been characterized as a dark and reddishP-type asteroid by theWide-field Infrared Survey Explorer (WISE), and as anX-type asteroid byPan-STARRS photometric survey.[3][5][10]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and theNEOWISE mission of NASA's WISE space-telescope,Amazone measures between 63.9 and 73.6 kilometers in diameter and its surface has analbedo of 0.039 to 0.054.[4][5][6][7] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.036 and a diameter of 73.6 kilometers.[3]
In April 2005, astronomerBrian Warner obtained two divergent rotationallightcurves forAmazone. The longer solution gave a longrotation period of 540 hours with a brightness variation of 0.25magnitude (U=2) The astronomer assumes the full lightcurve to be bimodal, having two maximums and minimums per rotation.[9][a]
Based on a proposal by Gustav Stracke, the asteroid was named after theAmazons, a race of woman warriors in Greek mythology. They had no men and joined with their neighbors, killed the sons and educated the daughters of whom the teats were burnt so that they could discharge the arrows more rapidly. The asteroids271 Penthesilea and10295 Hippolyta were named after queens of the Amazons, while5143 Heracles was named after the hero who fought them.[2]
