Summary edit

Description
Français : Ratio des isotopes de l’azote 15N/14N (en bleu)

mesurés en différents endroits du système solaire

Ecart par rapport au ratio actuel sur Terre. Les mesures effectuées par les sondes spatiales SoHO et Galileo présentent une incertitude précisée par les barres inférieure et supérieure. Le ratio de la Terre à l'origine est déduit du ratio des isotopes de néon et supposé lié à un processus d'échappement atmosphérique. Les valeurs hétérogènes pour les météorites et le régolite lunaire résultent des mesures directes effectuées sur des échantillons..
