C. Watson on April 3, 1872, and named after Althaea, the mother of Meleager in Greek mythology. Two occultations by Althaea were observed in 2002, only a month apart.March 2026 This object is orbiting the Sun at a distance of 2.58 AU with an eccentricity of 0.08, bringing it as close as 2.37 AU and taking it as far as 2.79 AU over the course of its 4.15 year orbital period. The orbital plane is inclined at an angle of 5.78° relative to the plane of the ecliptic. Based upon its spectrum, this is classified as an S-type asteroid. Using infrared measurements, its diameter was measured as around 57 km. Photometric observations made in 1988 at the Félix Aguilar Observatory produced a light curve with a period of 11.4840.010 hours with a brightness variation of 0.3650.010 in magnitude.
