HD 137010 (also known as EPIC 249661074) is a solar analog star located approximately 146 light-years away in the zodiac constellation of Libra. Its apparent visual magnitude is 10.14, making it invisible to the naked eye but observable with a standard telescope. It likely has an orbiting exoplanet, known as HD 137010 b, which may be a very Earth-like exoplanet in terms of orbital characteristics but cooler than Earth.
