• Resumen

  • The article discusses a study by astronomers Mary Anne Limbach and Edwin L. Turner, published in the January 2015 issue of "Proceedings of the National Academy of Sciences USA," which suggests that a greater number of planets in a solar system creates a more circular orbit of a star's planets, causing the planets to not move toward or away from their star and creating stable climates that may foster advance life. Graphs are presented of the number of planets and the orbits of planets.
