(8597) Sandvicensis is an asteroid of the central main 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 .
The asteroid belongs to the Eunomia family, a group named after (15) Eunomia , to which probably five percent of the asteroids in the main belt belong. The timeless (not osculating ) orbital elements of (8597) Sandvicensis are almost identical to those of the smaller, if one of the absolute brightness emanating from 16.0 versus 13.0, asteroid (298170) 2002 TS 145 .
(8597) Sandvicensis is named after the sandwich tern , whose scientific name is Sterna sandvicensis . At the time the asteroid was named on February 2, 1999, the sandwich tern 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 .
