• Resumen

  • This article focuses on gravity-related theories about the retrograde orbit of Neptune's moon Triton and the tilt of Uranus's axis relative to the planet's orbital plane. Astronomers theorize that if a pair of objects orbiting each other passed by Neptune, the slower one might have been caught by Neptune while the other continued on. They also think that the gravity of Saturn's wobbling spin could have nudged Uranus on its side during close encounters of the pair.
