Ekvatorial koordinatalar tizimi

Ekvatorial koordinatalar tizimi samoviy jismlarning joylashishini aniqlash uchun keng qo?llaniladigan samoviy koordinatalar tizimidir . U sferik yoki to?rtburchak koordinatalarda amalga oshirilishi mumkin, ikkalasi ham Yerning markazi, Yer ekvatorining samoviy sferaga proyeksiyasidan (osmon ekvatorini tashkil etuvchi) asosiy tekislik, bahorgi tengkunlik tomon birlamchi yo?nalish va o?ng qo?l bilan belgilanadi ^[1]^[2].

Koordinatalar boshi Yer markazidaligi bu koordinatalarning geosentrik ekanligini, ya?ni Yerning markazidan u xuddi shaffof bo?lganidek ko?rinib turganini bildiradi ^[3]. Asosiy tekislik va asosiy yo?nalish koordinatalar tizimi Yerning ekvatori va qutbiga to?g?ri kelganda, Yer bilan aylanmasligini, lekin fondagi yulduzlarga nisbatan o?zgarmasligini anglatadi. O?ng qo?l qonuni koordinatalar asosiy tekislik atrofida shimolga va sharqqa qarab oshishini anglatadi.
