HD 15115 is a star in the constellation Cetus. Its apparent magnitude is 6.76. Located approximately 48.2 parsecs (157 ly) distant, this F4 subgiant was shown to have an asymmetric debris disk surrounding it. The reason for the asymmetry is thought to be the gravitational pull of a companion star, an exoplanet, or interaction with the local interstellar medium.[6]
