Astronomers surprised to find planet 'too massive for its star'
Astronomers surprised to find planet 'too massive for its star'
The discovery of planet LHS 3154 b challenges the prevailing planetary formation theory involving red dwarfs, as it is much larger than expected. The planet, orbiting a red dwarf called LHS 3154, has a mass 13 times that of Earth and a mass ratio over 100 times greater than that of Earth and the sun. The planet's close proximity to its star and its probable Neptune-like composition make it unlikely to support life. This discovery raises questions about how planets form around low mass stars, which were believed to only produce small terrestrial planets.
