Mars is an “Embryo” planet

Scientists have determined that Mars is an “Embryo” planet, which stopped in his development of tens of millions of years ago.Poorman and Nicholas Dofas argue that Mars was formed just two million years after the occurrence of the solar system, is ten times faster than the Earth, which explains, in particular, its small size. Previously, scientists believed that the formation of Mars took no more than 15 million years.Scientists have conducted a comparative analysis of meteorites-chondrites and meteorites of Martian origin for determining the age and composition of the mantle of Mars. Scientists have compared the two parameters, the relation of share of hafnium and tungsten, and the isotopic composi tion of tungsten in the mantle of Mars.

The period half-life of hafnium-182 into tungsten-182 is 9 million years. This means that virtually all Hafnium should disappear in 50 million years.So a more exact valuation of the content of hafnium and tungsten in the mantle give scientists the opportunity to understand that Mars is an unformed “Embryo” planet.
