Those theories got a jolt 10 years ago, when astronomers first began discovering planets outside our solar system orbiting other stars.

This scenario naturally produces a planetary system just like our own: small, rocky planets with thin atmospheres close to the star, a Jupiter - like gas giant just beyond the snowline, and the other giants getting progressively smaller at greater distances because they move more slowly through their orbits and take longer to hoover up material.

In my 2013 science - fiction novel Proxima I imagined a habitable planet orbiting the red dwarf Proxima Centauri, the nearest star to our solar system.
