Astronomers discover 'unique inside-out system' with a rocky planet far from where it belongs

Astronomers have discovered an unusual planetary system with a rocky planet far from where it belongs, challenging current theories of planet formation. The system, orbiting the red dwarf star LHS 1903, includes four planets, with the rocky planet forming at its outer edge, beyond the gas giants. This discovery suggests that planets can form in environments depleted of gas, contrary to previous understanding.
