10247 Amphiaraos rotation period of 34.26 hours and possibly an elongated shape.[4] It was named after the seer Amphiaraus (Amphiaraos) from Greek mythology.[1]
Orbit and classification
Amphiaraos is a Jovian
semi-major axis of 5.26 AU). Its orbit has an eccentricity of 0.01 and an inclination of 4° with respect to the ecliptic.[3] The body's observation arc begins with its official discovery observation at Palomar in September 1960.[1]
Palomar–Leiden survey
The
survey designation "P-L" stands for Palomar–Leiden, named after Palomar Observatory and Leiden Observatory, which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with the discovery of several thousand asteroid discoveries.[13]
Physical characteristics
Amphiaraos has been characterized as an X and D-type asteroid in the SDSS-based taxonomy,[11] and by Pan-STARRS' survey.[10] It is also an assumed C-type.[4]

Diameter and albedo
According to the survey carried out by the
albedo of 0.098,[7][8] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 33.54 kilometers based on an absolute magnitude of 11.1.[4]
