so after earning needed credits from bounty hunting, I bought a Cobra and fitted the ship for exploring (I call her Morris

I've already managed to discover my first Earth-like planet (not discovered by anyone else, hope I earn some fame for it), several giants with water based life and ammonia life.
So far no accidents.
I have one Q for fellow explorers, how common is high metal content planet with oxygen atmosphere? I have found plenty of HMC but only one with this kind of atmosphere.
