(8586) Epops is an asteroid of the outer main belt , which was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The asteroid belongs to the Themis family, a group of asteroids named after (24) Themis . The ageless (not osculating ) orbital elements of (8586) Epops are almost identical with those of four smaller, when one of the absolute brightness starting from 14.6, 14.5, 16.2 and 15.7 versus 12.7, asteroids : (48791) 1997 SD 33 , (69197) 1238 T-2 , (187730) 2008 FX 66 and (228980) 2003 UZ 289 .
(8586) Epops is named after the hoopoe , whose scientific name is Upupa epops . At the time the asteroid was named on February 2, 1999, the hoopoe was on the Dutch Red List of Endangered Species . The first letters of the asteroids (8585) to (8600) form the phrase Per aspera ad astra . The asteroid of the central main belt (2868) Upupa , discovered in 1933 and named on November 10, 1992, is named after the hoopoe .
