(8596) Alchata is an asteroid of the main inner belt that was discovered on September 29, 1973 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made during the 2nd Trojan survey, during which Tom Gehrels surveyed field plates recorded with the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 13 years after the start of the Palomar-Leiden- Surveys .
In a publication from 1995 (et al.), The Italian astronomer Vincenzo Zappalà defines an asteroid belonging to the Flora family, a large group of asteroids named after (8) Flora . Asteroids of this family move in a 4: 9 orbital resonance with the planet Mars around the sun . The group is also called the Ariadne family, after the asteroid (43) Ariadne .
(8596) Alchata is named after the pomeranian chicken , whose scientific name is Pterocles alchata . At the time the asteroid was named on February 2, 1999, the pomeranian grouse was on the European Red List of Endangered Species . The first letters of the asteroids (8585) to (8600) form the phrase Per aspera ad astra .
