Jam astronomis

Jam astronomi, di Alun-Alun Kota Tua, Praha.

Jam astronomi, Horologium, atau Orloj adalah jam dengan mekanisme khusus dan cakra angka untuk menampilkan informasi astronomi, seperti posisi relatif dari matahari, bulan, konstelasi zodiak, dan terkadang planet-planet utama.

Sebuah penelitian dari sekelompok ahli pada tahun 2011 dan 2012 berpendapat bahwa jam astronomi Eropa berasal dari teknologi mekanisme Antikythera.[1]
