Researchers from the University of Johannesburg who have studied the composition of the space stone known as Hypatia, a unique meteorite found in Egypt in 2013, is that it is formed by matter that existed in space before our Sun was formed, the Earth and the other planets in our solar system.

Hypatia

The original extraterrestrial rock that fell to Earth must have been at least several meters in diameter, but disintegrated into small fragments of which the Hypatia stone is one. According to Jan Kramers , principal investigator:

We can think of the badly mixed mass of a fruit cake that represents most of the Hypatia pebble, what we call two mixed ‘matrices’ in geological terms. The glace cherries and walnuts on the cake represent the mineral grains found in Hypatia inclusions. And the flour that sprinkles the cracks of the fallen cake represents the ‘secondary materials’ that we find in the fractures of Hypatia, which are from the Earth.

The Hypatia matrix has a massive amount of carbon and an unusually small amount of silicon, and also a lot of very specific carbon compounds, called polyaromatic hydrocarbons, or PAH, a major component of interstellar dust, that existed even before our solar system will be formed.

There are also grains of a compound consisting mainly of nickel and phosphorus, with very little iron, a mineral composition never before observed on Earth or in meteorites.

These and other particularities in the composition of Hypatia makes it suppose that it has remained intact since before the formation of the Solar System.
