Researchers have located “the perfect solar system”, forged without the violent collisions that made our own a hotchpotch of different-sized planets.
The system, 100 light years away, has six planets, all about the same size. They’ve barely changed since its formation up to 12 billion years ago.
These undisturbed conditions make it ideal for learning how these worlds formed and whether they host life. The research has been published in the scientific journal, Nature.
