LHS 1140 d is an exoplanet located about 40 light-years away in the constellation of Centaurus. It orbits a red dwarf star known as LHS 1140 and is classified as a super-Earth, meaning it is larger than Earth but smaller than gas giants like Neptune. This planet is particularly interesting because it lies within the star's habitable zone, where conditions might allow for liquid water to exist. LHS 1140 d has a mass approximately 6.5 times that of Earth, and its discovery has provided valuable insights into the characteristics of rocky planets outside our solar system.
