Toronto, Dec 18 (Canadian-Media): A study published in the journal Earth and Planetary Science Letters challenges the the assumption that Mars formed near Earth from the same building blocks, media reports said.
Mars was reportedly formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current position, before migrating to its present location.
Moreover the two planets have different compositions. Mars contains different, lighter, silicates than Earth, more similar to those found in meteorites.

Researchers from Japan, the United States and the United Kingdom ran simulations to gain insights into the Red Planet's movement within the solar system to explain why the elements and isotopes on Mars differ widely from those on Earth.
In these simulations, the researchers gleaned additional insight into Mars' formation. A small percentage of the simulations suggested that Mars formed much farther from the sun than it is now and that Jupiter's gravitational pull pushed Mars into its current position.
