Astronomers still aren't exactly sure how planets get their start.

Giant impact modeling seems to be great fun, however, showing how such catastrophism operating in the early solar system created various planets as this space.com article indicates, is more difficult The giant impact model for the origin of the Moon is now used to explain the origin of a reducing atmosphere on the early earth so abiogenesis can take place.

Planetary scientists simulate oxidation of iron by giant impact during atmospheric evolution of early Earth, https://phys.org/news/2023-12-planetary-scientists-simulate-oxidation-iron.html

Ref - Oxidation of iron by giant impact and its implication on the formation of reduced atmosphere in the early Earth, https://www.science.org/doi/10.1126/sciadv.adi6096, 15-Dec-2023. "Abstract Giant impact–driven redox processes in the atmosphere and magma ocean played crucial roles in the evolution of Earth..."

So far, I do not see this model explanation for a reducing atmosphere allowing abiogenesis to create life on the early earth, applied elsewhere in the solar system. This sites shows 5581 confirmed exoplanets now, https://exoplanet.eu/home/

3994 exoplanets show radii property. Out of this selection, 324 exoplanets show radii 0.8 to 1.2 earth size. I have not seen any reports that confirm exomoons or giant impacts creating moons on the known exoplanets to date or how giant impacts created the population of smaller, earth size exoplanets too.
