Multiple formation and evolution paths, however, can result in the same planetary architecture. Because of this, unveiling the individual histories of planetary systems and their planets can prove a challenging task. The chemical composition of planets provides us with a guiding light for navigate ...
“Our results show that our assumptions regarding star and planet compositions were not fundamentally wrong: the composition of rocky planets is indeed intimately tied to the composition of their host star. However, the relationship is not as simple as we expected,” lead author of the study and...
Lewismaintains that condensation from a homogeneous nebula under differing physical conditions can account for the density variation between the inner planets without invoking the metal-silicate fractionation suggested by Urey. Compared to the above hypotheses based on meteorite composition, the following ...

which resulted in the formation of multiple dust particles and gas. Gravity acted upon these fragments, which began to orbit around the Sun. Over time, the shrapnel from this explosion would eventually combine to form theplanets, as well as many of the smaller celestial bodies found in the so...
Not all astronomers and planetary scientists agreed with the definitions, with some seeing them as limiting the number of planets and others finding them incomplete and confusing. Certain astronomers stressed the importance of considering the context for understanding the solar system’s formation and ev...
