El nacimiento del Sistema Solar

The solar system formed around 5 billion years ago from a rotating cloud of gas and dust. Under gravity, the core of this cloud became dense and hot, leading to nuclear fusion and the birth of the Sun. Lighter gases moved outward, while heavier materials formed rocky planets near the Sun. In colder regions, ice and gas accumulated, forming gas giants. The solar system is approximately 4.6 billion years old and well-preserved.
