What is the diffrence between primordial and cptured moon (orbit)?
Well, there’s really little if any difference in this context between “primordial” and “capture moon.” The word “primordial” itself means “at the very earliest time.” For example, ‘Earth’s primordial oceans were very different than they are today,’ or ‘The primordial universe was much hotter than it is today.’ In the case of the moon “primordial” simply refers to the moon in its infancy or just after it became a satellite of Earth. The “capture moon” refers to one of the theories about the moon’s origins, in this case that it formed somewhere else and somehow became captured by Earth’s gravity.
