Researchers have located "the perfect solar system", forged without the violent collisions that made our own mix of different-sized planets.

The system, 100 light years away, has six planets all about the same size and is thought to have been formed up to 12 billion years ago.

The creation of our own solar system was a violent process, with planets crashing into each other, disturbing orbits and leaving us with giants like Jupiter and Saturn alongside relatively small worlds like our own.

In solar system HD110067, as astronomers have named it, things couldn't be more different and these undisturbed conditions make it ideal for learning how these worlds formed and whether they host life.
