Title: AN ODD PLANETARY SANDWICH LEAVES ASTRONOMERS HUNGRY FOR ANSWERS.
Authors: Mann, Adam (AUTHOR)
Source: Science News. May2026, Vol. 208 Issue 5, p35-35. 1/3p.
Subjects: Planetary systems, Gas giants, Inner planets, Dwarf stars, Origin of planets, Astronomy
Abstract: The article focuses on the unusual planetary system of the star LHS 1903, a red dwarf about 116 light-years from Earth, which hosts four planets arranged with two rocky planets sandwiching two gaseous ones. This configuration challenges typical planetary formation models, where rocky planets form closer to the star and gas giants farther out. Astronomer Andrew Cameron and colleagues suggest that inward migration of the gaseous planets or a violent event, such as a collision stripping the atmosphere of the outermost planet, could explain this arrangement. The findings offer insights into planetary system evolution and may refine existing theories. [Extracted from the article]
