LHS 1478 and Its Earth-Like Planet
LHS 1478 is an M-type main-sequence star, a small, cool red dwarf, located 59.5 light-years away. A single planet orbits this star, and it is an Earth-like world detected by the transit method in 2021, when the planet's passage in front of the star caused a small dip in observed brightness. LHS 1478 b completes an orbit every 1.95 days.
The star's reported mass estimate is 0.236 solar masses, and its reported radius estimate is 0.246 solar radii. Its temperature is 3380 K, which is cooler than the Sun's.
LHS 1478 b has a mass of 2.33 Earth masses and a radius of 1.24 Earth radii, making it larger in both size and mass than Earth. Its mean density is 6.7 g/cm³, 1.22 times Earth's.
