HD 15115 is a star in the constellation Cetus. Its apparent magnitude is 6.79.[2] Located approximately 45.23 parsecs (147.5 ly) distant,[1] this F-type star 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.[3]
