1924 Horus, also designated 4023 P–L, is a main-belt asteroid discovered on September 24, 1960 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld at Leiden, on photographic plates taken by Tom Gehrels at Palomar. On the same date, the trio of astronomers also discovered 1912 Anubis, 1923 Osiris and 5011 Ptah.[3]
Horus measures about 12 kilometers in diameter.[1]
The designation P–L stands for Palomar–Leiden, named after Palomar Observatory and Leiden Observatory, which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld at Leiden Observatory. The trio are credited with several thousand asteroid discoveries.
It is named after Horus, the falcon-headed king of the sky and the stars, and son of the Egyptian god Osiris.[2]
