Comprendre comment notre Terre s’est form\u00e9e est un grand d\u00e9fi de la science plan\u00e9taire<\/span><\/strong>, et au c\u0153ur de la recherche d’autres plan\u00e8tes habitables dans la Galaxie. Nous avons des images de disques de formation de plan\u00e8tes autour de jeunes \u00e9toiles et nous avons d\u00e9couvert des milliers d’exoplan\u00e8tes. On pense que divers processus physiques sont responsables de la croissance de grains de poussi\u00e8re de taille microm\u00e9trique sur des plan\u00e8tes de plusieurs dizaines de milliers de kilom\u00e8tres. Certains processus se comportent bien et sont pr\u00e9visibles. Pourtant, d’autres sont de nature stochastique, de sorte qu’un petit changement peut entra\u00eener un r\u00e9sultat radicalement diff\u00e9rent.<\/p>\n

Les simulations num\u00e9riques peuvent nous aider \u00e0 explorer la robustesse de la formation de notre plan\u00e8te et de notre syst\u00e8me solaire.\u00a0 <\/strong><\/p>\n

La question devient alors : quelles caract\u00e9ristiques rendent la Terre vraiment \u00ab sp\u00e9ciale \u00bb ?<\/strong><\/span><\/p>\n
