LHS 1140 b
LHS 1140 b is a massive, dense rocky planet orbiting within the conservative habitable zone of the red dwarf LHS 1140. Discovered in 2017 by the MEarth Project, LHS 1140 b is nearly 7 times the mass of Earth and over 60% larger in radius, putting it within the Super-Earth category of planets. It is one of the densest planets found, with a density more than twice that of Earth, along with a high surface gravity of about 2.41 Earth's. LHS 1140 b orbits entirely within the star's habitable zone and gets 41% the incident flux of Earth. The planet is only 40 light-years away and transits its star, making it an excellent candidate for atmospheric studies with ground-based and/or space telescopes.
