Glossary term: 日心模型
Description: 日心說一詞源自希臘語，其中“helios”是太陽的意思，“kentro”意為中心。該模型將太陽置於太陽系的中心，行星圍繞它運行，取代了地心說（以地球為中心的模型）。儘管日心說的起源通常歸功於16世紀的哥白尼，但早在的古希臘時期，薩摩斯的阿里斯塔克斯就提出了日心模型，印度、歐洲和伊斯蘭世界的天文學家也在哥白尼之前討論過類似的模型。伽利略通過望遠鏡觀測金星的運動，提供了日心說的觀測證據。最初的日心模型將太陽置於太陽系的幾何中心；這一觀點隨著開普勒對第谷·布拉赫數據的數學推導而發生變化，後來牛頓通過萬有引力定律進一步完善和擴展了這一理論。
