“It is great to know that radioactive elements can help make a wet system drier and to have an explanation as to why planets within the same system would share similar properties,” says Meyer. “But radioactive heating may not be enough.

Perhaps having Jupiter where it is was also important in keeping most icy bodies out of the inner solar system.”
