La composizione tipica dei meteoriti ricorda la
composizione dei nuclei e mantelli planetari, nonchè della crosta planetaria.
Secondo il modello di Ackerman la stragrande maggioranza dei meteoriti
provengono da Marte. Notare ora la strana serie di orbite di questi asteroidi
che transitano nel sistema solare interno. Nonostante tutte le congetture
possibili, potremmo ben vedere in essi qualche ulteriore indizio a favore della
catastrofe planetaria nel nostro sistema solare.









I
meteoriti marziani. C’è una
succinta quantità di meteoriti caduti sulla Terra che, dopo l’analisi, sono
stati catalogati come “frammenti del pianeta Marte” (così affermano alla
NASA). E non sono pochi! Con tutta probabilità ne verranno trovati degli
altri….
