After 5 billion years (50000 million years), the sun becomes a red superstar and the surface temperature drops to 2000 degrees Celsius. And the temperature of the core (the center of the sun) will rise to 100 million (100000 000 ℃)! ! ! At that time. The volume of the sun will continue to expand. The volume is 10000 times that of the original sun! The sun will devour Mercury, Venus, even Earth, Mars, and eventually, he will explode. Turn into a hot, secret white dwarf whose surface temperature will be 100 million degrees Celsius and is not swallowed up by celestial bodies. Either continue to revolve around the sun, or the cold wind is piercing to the bone. After that, the sun will become a black dwarf, when the surface temperature of the sun will drop to minus 20 ℃. At that time, the sun will become a dark star. Or a neutron star. Maybe it"s a black hole. Maybe. . . . . .
太陽的大結局：
50億年後（5000000000000年）後，太陽變成紅巨星，表面溫度會降至2000攝氏度。而核心（太陽中心）的溫度會升至1億（10000000000℃）！！！
屆時。太陽的體積將不斷的膨脹。體積是原來的太陽的10000倍！
太陽將吞噬水星，金星，甚至是地球，火星，
最後，他會爆炸。變成一個又燙又秘製的白矮星，它的表面溫度會是1億攝氏度，而沒被吞噬的天體們。要麼繼續圍繞太陽公轉，要麼寒風刺骨。
之後太陽就會變成一顆黑矮星，屆時，太陽的表面溫度會降至零下20℃。
屆時太陽將會變成一顆黑暗的恆星。或者是中子星。也許是黑洞。也許………………
