Parsek
Parsek (parallaks va sekunda) — astronomiyada Quyosh sistemasidan tashqaridagi osmon jismlarigacha boʻlgan masofani aniqlashda qoʻllaniladigan oʻlchov birligi. Qisqacha ps (xalqaro birligi pc) bilan belgilanadi. Bir Parsek 3,26 yorugʻlik yiliga, 206 264,8 astronomik birlikka yoki 30,857–1012 km gateng. 1 kiloparsek=103 parsek, 1 megapar-sek =106 parsek. Parsekda ifodalangan masofa yillik parallaksga teskari miqdor hisoblanadi. Masalan, 10 pk ga teng masofa 0,1" parallaksga mos keladi.[1]
1 parsek = astronomik birlikka ≈ astronomik birlikka ≈ 206 264,8 astronomik birlik = 3,0856776×1016 m = 3,2616 yorugʻlik yili
