• An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. • Across our galaxy, astronomers routinely observe a characteristic pattern in planetary systems: rocky planets orbiting close to their host star with gas giants farther away. • Our own solar system follows this rule, with the inner planets: Mercury, Venus, Earth and Mars, composed of rock and iron, and the outer planets: Jupiter, Saturn, Uranus and Neptune being predominantly gaseous.

  • An international team of astronomers has identified a distant planetary system that defies the conventional model of planet formation. Traditionally, observations across the Milky Way show a clear arrangement: rocky, terrestrial planets orbit close to their host star, while gas giants reside farther out, a pattern mirrored by our own Solar System. The newly discovered system, however, displays a different configuration, with gas‑rich planets located unusually close to the star and rocky bodies farther away. This anomaly challenges existing theories and suggests that planet‑formation processes may be more varied than previously thought.
