Sistem koordinat astronomi

Sistem koordinat astronomi adolah pangaturan taorganisir untuak manantuan posisi dari satelit, planet, bintang, galaksi, jo bando-bando langik lainnyo, sacaro relatif taradok titiak-titiak rujuakan fisik nan tasadio, untuak pangamat nan barado di tampek tatantu (misanyo mamakai cakrawala sajati jo arah mato angin utara untuak pangamat nan barado di muko bumi). Sistem koordinat dalam astronomi dapek manantuan latak obyek dalam ruang tigo dimensi, atau mambuek plot arahnyo sajo pado bola langik, jikok jarak obyek tu indak dikataui atau indak pantiang.

Sistem koordinat bola nan diproyeksikan pado bola langik, dapek disamoan jo sistem koordinat geografis nan bapakai di Bumi. Namun, kaduonyo balain dalam bidang fundamental nan dipakai, nan mambagi duo bola langik manjadi duo hemisfer di sapanjang lingkaran gadang. Sistem koordinat Cartesius, dalam satuan ukua, punyo bidang fundamental () jo arah primer (sumbu ) nan samo, co pado sumbu rotasi tatap tatantu. Tiok sistem koordinat dinamoan sasuai jo bidang fundamental nan dipakainyo.
