تشكل الشمس (Info)
تشكلت الشمس قبل حوالي 4.6 مليار سنة، ويُعتقد بأن الشمس وبقية النظام الشمسي قد تشكلت من سحابة عملاقة من الغاز والغبار والتي تعرف باسم السديم الشمسي، وبسبب انهياره تم سحب معظم المواد باتجاه المركز وبهذا تشكلت الشمس، كما تمتلك الشمس كمية كبيرة من الوقود النووي الذي يكفيها للبقاء لحوالي خمسة مليارات سنة أخرى.
