Planetary migration is the most likely explanation for hot Jupiters ( exoplanets with Jovian masses but orbits of only a few days). Or the last collisions may have knocked Venuss rotation axis to its weird angle and slowed its rotation rateyet these collisions did not produce a moon. They formed farther out like Jupiter but then migrated inward. Nature (Nature) Astron. Izidoro, A., Dasgupta, R., Raymond, S.N. volume505,pages 629634 (2014)Cite this article.

P., Morbidelli, A. What could have caused the planets to migrate through the solar system Scientists have long hypothesised the bombardment was caused by planetary migration, as Jupiter and Saturn moved closer in towards the Sun, while Neptune and Uranus moved further out from where they formed. Do you know that raindrops come from clouds in the sky? We use a series of simulations to follow the evolution of the innermost ring and show how it can explain the orbital structure of the inner Solar System and provides a framework to explain the origins of isotopic signatures of Earth, Mars and different classes of meteorites.
