A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.
Astronomers have found a compact solar system whose planets line up in a way that, according to current models, should not be possible. Around the small star LHS 1903, a dense rocky world orbits on ...
A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.
The fourth planet in the system is a rocky world, while the second and third ones are gas planets.
A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.
