How the moon was formed?

Re: How the moon was formed?

@TLK

^ i agree. Option 3 does not sound right for another reason. Our solar system has total of 168 moons orbiting the planets. If we caught our moon then same must be true for all the other moons. Fishing168 huge wandering bodies from this amazing emptiness of space sounds little unbelievable.

But then if option 3 sounds inconceivable because probability of it repeating itself 168 times is very very little, then so is the probability of option 1 repeating itself that many times.

I think that all the moons were made out of the same dust that created their parent planets. It’s just that it took longer for the moon’s dust to condense, hence the age difference.

A moon forming from a collision or with the leftover stellar dust from planet formation, the two are not mutually exclusive. The end result could or could not be similar mineral makeup of the planet and its moon. A planet in the making can sustain many collisions but those collisions may or not help form a moon or moons.
