Solar System is Older


The solar system could be up to two million years older than previously thought. Analysis of a meteorite found in the Sahara desert has indicated that the solar system is at least 4.5682 billion years old. By using a technique known as lead-lead dating, scientists calculated the age of a calcium and aluminumrich inclusion within the meteorite.

Inclusions are the first solids to form during the birth of the solar system. The revision is significant since the solar system is shaped within the first 10 million years of its formation. It can be deduced that solar system originated from supernovae and there was twice the amount of an iron isotope present in it.
