The oldest astronomical bodies are likely the stars in the universe, which formed around 13.8 billion years ago. Next are galaxies, which began forming shortly after the Big Bang. Planets, moons, asteroids, and other smaller bodies in our Solar System are relatively younger, with Earth estimated to be around 4.5 billion years old.
