NASA/JPLThe planets Uranus and Neptune are similar in many ways. Simulations show how different collisions produce different worlds. While earlier studies have modeled collisions with Uranus, this work looked at collisions with both Uranus and Neptune. After modeling various collision scenarios, the team found that Uranus likely had a more glancing collision with a large body. Planetary collisions were quite common in the early solar system, so it is not surprising that both worlds experienced collisions.
