HD 7853 is a double star in the constellation Andromeda. With an apparent magnitude of 6.46, the stars can barely be seen with the naked eye even on the best of nights. The system is located approximately 128.5 parsecs (419 ly) distant, and the brighter star is an Am star, meaning that it has unusual metallic absorption lines.[2]
