its neighbouring planet Mars and built the strange icy rocky asteroid belt billions of years ago when the solar system was forming, a new study has suggested. The unexpectedly smaller size of Mars and the strange asteroid belt located between the
orbits of the red planet and its neighbour Jupiter have long puzzled scientists. Now, an international team of scientists claimed to have found an explanation by carrying out computer simulations of the early solar system.
Their research showed that some 4.6 billion years ago when the solar system was forming, Jupiter went wandering in towards the Sun, on the way dragging comets from beyond the asteroid belt as it moved inwards towards Mars. It then moved out again to gravitate towards another gas giant, Saturn, as it formed, this time dragging dry rocks from inside the belt as it moved back outwards again.
