كم تساوي السنه الضوئية؟

السنة الضوئية مقياس فلكي للمسافات الهائلة بين الأجرام السماوية

وتُعرف السنة الضوئية بمقدار المسافة التي يقطعها الضوء بسرعته الهائلة 300000 كيلومتر في الثانية الواحدة خلال سنة كاملة

فالسنة الضوئية الواحدة إذاً تساوي:

365 يوم × 24 ساعة × 60 دقيقة × 60 ثانية × 300000 كيلومتر

وتساوي تقريباً

9500000000000 كيلومتر فقط
