Planet-Shifting Collision Shaped Uranus’ “Rolling” Rotation https://www.nasa.gov/feature/ames/pla... “Scientists have always wondered how Uranus got tilted so much that it spins on its side, and now research on the planet’s early formation gives us new insight.”
Two Worlds Collide in Deep Space https://www.space.com/7116-worlds-col... “The two-planet pileup occurred within the last few thousand years or so - a relatively recent cosmic timeframe. The smaller of the two bodies - a planet about the size of Earth's moon, according to computer models - was apparently destroyed by the crash. The other was most likely a Mercury-sized-planet and survived, albeit severely dented.”
Earth’s Moon | In Depth https://solarsystem.nasa.gov/moons/ea... “The leading theory of the moon's origin is that a Mars-sized body collided with Earth about 4.5 billion years ago. The resulting debris from both Earth and the impactor accumulated to form our natural satellite 239,000 miles (384,000 kilometers) away.”
