Formation of the Planets

Evolution of Planets: Planetary Transformations Over Billions of Years Earth evolved from a fiery young world into the life-filled blue planet we know today. Venus, once possibly Earth-like, became an extreme greenhouse world with scorching 800°F temperatures. Mars shifted from warm and wet to cold and dry as it lost its atmosphere and water. Saturn’s famous rings are relatively young, forming 100–400 million years ago from a shattered moon or comet.#einstein #NASA #atomico #blackholes #astronom
