Regarding the likely chemical composition of earth-like planets - would the distance of a planet from its star change the relative abundance or poverty of certain elements? Or would other factors, like the number of planets in the solar system or the type of star, be a greater influence?
I ask because I'm wondering if a space mining company would, seeking specific elements, search for planets which were hot or cold knowing they'd likely yield specific elements? Or would that be of secondary importance? And if so, to what factors?
