Template: Infobox Asteroid / Maintenance / Error 2

( 10247 ) Amphiaraos is an asteroid from the group of Jupiter Trojans. Thus asteroids are called, which run on the orbit of the planet Jupiter on the Lagrange points around the sun. He is associated with the Lagrangian point L4, ie ( 10247 ) Amphiaraos runs Jupiter in its orbit around the sun at 60 ° ahead.

The asteroid was discovered on September 24, 1960 by the Dutch astronomer Cornelis Johannes van Houten couple and Ingrid van Houten - Groeneveld. The discovery came as part of the Palomar - Leiden Survey, which recorded by Tom Gehrels with the 120 - inch Oschin Schmidt telescope at Palomar Observatory field plates at Leiden University were screened.

The eccentricity of the asteroid is low at 0.0088, so that its orbit around the sun is quite close to an ideal circular path, similar to the eccentricity of the planet Neptune ( 0.0086 ). It is still significantly less than the eccentricity of the Earth ( 0.0167 ).

The rotation period of ( 10247 ) Amphiaraos was determined in February and March 2011 by Robert Stephens during a guest stay at the Goat Mountain Astronomical Research Station ( GMARS ) in Rancho Cucamonga, California with 34.26 (± 0.01) hours. This means that the asteroid is unusually slow turns around itself

( 10247 ) Amphiaraos was named after Amphiaraus, a seer of Zeus and generals from Argos. The appointment took place on 24 January 2000. Forward in advance Trojans are named after the Greek hero.
