This discovery confirms the main hypothesis of the origin of rocky planets. Published in an article in Science Advances, the researchers identified the exact isotopic composition of both planets and compared them to isotopic analysis of meteorites from both within and outside the solar system. There is a theory that the isotopes in the early solar system were unevenly distributed, which allows us to determine the material from which a particular celestial body is formed. In total, scientists analyzed the composition of 17 Martian meteorites and revealed the presence of titanium, zirconium and molybdenum. In order to reproduce the isotopic composition of Mars and our planet, experts also modeled the proportion of material coming from the inner and outer space of the solar system. Mars has little in common with the outer space meteorites of the solar system, only about 4%. The isotopic composition of matter formed outside Jupiter’s orbit is known to form carbonaceous chondrites, which have a high carbon content. The material in the interior of the Solar System is made up of non-carbonate chondrites. However, astronomers also discovered material that appeared near the sun, but is not present in non-carbonaceous chondrites, a type of meteorite made of dust and small particles from the early days of the solar system. This can be explained by the fact that this substance was completely used in the formation of rocky planets.

Space, Earth, Mars and the Solar System
Astronomers at the University of Münster in Germany have established that Mars and Earth were formed mainly from material from the inner part of the solar system and that only a small part originated outside the orbit of Jupiter.
In total, scientists analyzed the composition of 17 Martian meteorites and revealed Presence of titanium, zirconium, and molybdenum.
