HD 82741

HD 82741 is a G-type main-sequence star located approximately 117 light-years away in the constellation Hydra. The star is similar to the Sun in terms of temperature and spectral type, but is significantly older, estimated to be around 9 billion years old.

HD 82741 is notable for hosting three known super-Earth exoplanets: HD 82741 b, HD 82741 c, and HD 82741 d. These planets are all larger and more massive than Earth, and they orbit relatively close to their host star. They were discovered using the radial velocity method, which detects the slight wobble in a star's motion caused by the gravitational pull of orbiting planets.

The system is of interest to astronomers because the relatively high metallicity (abundance of elements heavier than hydrogen and helium) of HD 82741 suggests a different formation history compared to other star systems. The presence of three super-Earths in such a compact configuration poses challenges to planet formation theories and provides valuable data for understanding planetary system architecture. Further studies of HD 82741 and its planets aim to determine the composition and potential habitability of these super-Earths.
