New solar system models show Earth is no fluke

A paper presented at the Origins 2026 conference in Paris details innovative simulations of how our solar system might have formed without making assumptions about the planetary architecture we are familiar with. Nader Haghighipour, a planetary scientist at the University of Hawaii in Manoa, argues that his models incorporate many completely random starting points and let physics drive the models' ultimate evolution. These new models are more complete and allow physics to dictate their outcomes. Haghighipour and colleagues found that the formation of Earth at one Earth-sun distance is a natural outcome of the evolution of our solar system. They also found that Venus appears about 28% of the time and maintains its orbit, sometimes in the habitable zone of the stars, sometimes slightly outside, and Mars appears as a small object in the vicinity of the current orbit of Mars. The simulations, which previously took six to eight months to run, can now be done within six to eight weeks on current laptop computers.

The paper claims that the formation of Earth at one Earth-sun distance is a natural outcome of the evolution of our solar system. It also suggests that Venus and Mars can exist in different configurations, and that these configurations are not fixed but evolve over time. Haghighipour and colleagues' models simulate these hypothetical planetary bodies' interactions with one another. The study implies that the formation of Earth is not a special case but a natural outcome of the physical processes that govern solar system evolution.
