(8603) Senator is an asteroid of the inner main belt , which was discovered on October 16, 1977 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery took place during the 3rd Trojan survey, during which Tom Gehrels surveyed field plates recorded by the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 17 years after the start of the Palomar-Leiden- Surveys .
The mean diameter of the asteroid was roughly calculated as 3.047 (± 0.621) km , the albedo as 0.229 (± 0.018).
(8603) Senator is named after the red-headed shrike , whose scientific name is Lanius senator . At the time the asteroid was named on February 2, 1999, the red-headed shrike was on the Dutch and European Red Lists of Endangered Birds .
