According to evolutionary theories of planet formation, a newly-discovered Neptune-mass planet that orbits a small red dwarf star should not exist.1,2 Astronomers discovered this exoplanet (or extrasolar planet, a planet orbiting a star other than our sun) using an instrument constructed specifically for the purpose of detecting exoplanets orbiting low-mass stars. The red dwarf star has been designated LHS 3154, and the exoplanet... More...
