HD 3346, also known as V428 Andromedae, is a binary star[10] system in the northern constellation of Andromeda. It is a dim star but visible to the naked eye under suitable viewing conditions, having an apparent visual magnitude of 5.14.[5] The distance to HD 3346 can be determined from its annual parallax shift of 4.72 mas.[2] This yields a range of about 690 light-years (210 parsecs). At that distance the brightness of the system is diminished by an extinction of 0.16 magnitude due to interstellar dust.[11] It is moving closer to the Earth with a heliocentric radial velocity of −33 km/s.[11]
