Epsilon Eridani is a research area in astronomy that focuses on studying the star Epsilon Eridani, also known as 40 Eridani. It is a star system located approximately 10.5 light-years away from Earth in the constellation Eridanus. Epsilon Eridani is of particular interest to researchers because it is one of the closest star systems to our own solar system and has been extensively studied for its similarities to our Sun. Studies of Epsilon Eridani have provided valuable insights into the formation and evolution of planetary systems, as well as the potential for habitable planets in other star systems.
