Based on modeling estimates, scientists believe the asteroid Bennu has a 1-in-2700 chance of colliding with Earth. Seems like a safe bet that we’re going to be OK. But what if the space rock did strike our planet? @sciencefocus goes there:
Plusieurs ingrédients du vivant sur Bennu 
Des découvertes récentes révèlent la présence de nouveaux éléments essentiels à la vie. Ces résultats renforcent l’hypothèse selon laquelle des astéroïdes comme Bennu ont pu fournir les matériaux nécessaires à l’émergence de la vie sur Terre. (vidéo 2:17 min)

Salty brines on asteroids containing the building blocks of life, both Left (Earth dominant) and Right (not Earth dominant) handed amino acids have been found in Bennu's samples.
These brines are found on dwarf planets (Ceres) icy moons (Enceladus) and tiny asteroids like Bennu. It's everywhere....and could Life be everywhere it finds a way to make a living?
