Description: 木星是太陽系中最大的行星，也是距離太陽第五遠的行星。它是一顆氣態巨行星，半徑為 7.13 萬公里，大約是地球半徑的 11 倍。木星的質量（地球質量的 318 倍）比太陽系中所有其他行星和較小天體的總和還要大。

它與太陽的典型距離為 7.78 億千米，約為 5 個天文單位（地球與太陽的距離），完成一個軌道需要不到 12 年的時間。截至 2023 年，天文學家已經探測到 90 多顆圍繞木星運行的衛星或天然衛星。

它肉眼可見。它的英文名稱源自羅馬的眾神之王。用小型望遠鏡觀察，我們可以看到不同顏色的雲帶和一個巨大的紅色圓形風暴區（即所謂的大紅斑）。在過去的幾十年裡，已經有一些太空探測器被送往木星，2016 年，美國國家航空航天局的 "朱諾 "號宇宙飛船開始對木星及其衛星進行更詳細的探索。
