An ancient relic of our solar system’s early days, Bennu has seen more than 4.5 billion years of history. The best evidence suggests that within 10 million years of our solar system’s formation, Bennu’s present-day chemistry and mineralogy were already established. Because its materials are so old, Bennu represents a type of building block of our solar system’s rocky planets. It may even contain organic molecules similar to those that could have played a role in the start of life on Earth.

Tout cela est passionnant. ça me semble si lointain...
L'étude des comètes joue un rôle important également pour ce qui est d'établir un lien entre notre terre et son environnement stellaire ou sa formation. :)
