Its orbit shows an eccentricity of 0.13 and is tilted by 13 degrees to the plane of the ecliptic. It has a rotation period of 16 hours〔 and an albedo between 0.06 and 0.09, according to the surveys carried out by the IRAS, Akari, and WISE/NEOWISE missions.〔〔〔〔〔 The minor planet was named in honour of the North African country Algeria, location of the discovering observatory and a French colony at the time.〔 == References ==
