A Dream of a Twin Earth
What if a second Earth arrived, not to destroy, but to share space with us? In theory, it might be possible. A rare type of orbit called a horseshoe path could allow two planets to follow intertwined routes around the Sun. Saturn’s moons already do this.
If Earth had a twin in such a configuration, the two worlds might pass close to each other every few decades but never collide.
One could remain in permanent summer, the other in constant winter. Whether that would be paradise or problem depends on your perspective.
