119)Which planet was made first in the grand scheme of things, planet Mars or planet Earth?

From the same Economist article I quoted in my previous post(No.118) comes the knowledge that, based on isotope studies, planet Mars was formed before planet Earth when our Solar system was being created. This, despite the fact that planet Earth is the 3rd planet from the Sun and planet Mars is the 4th planet from the Sun:

"Isotopes can even indicate the order in which the planets formed. The decay products of a short-lived isotope called hafnium-187, also suspected of being formed in the supernova that brought aluminium-26 to the solar system, are rare on Earth. On Mars they are more abundant. This indicates that Mars formed before Earth, trapping hafnium-187 while there was still some around."
