HD 204521 is a potential Sun-like star (G5 spectral class) with an apparent magnitude of 7.3.[1] In the sky it is near the magnitude 3.2 star Beta Cephei (β Cep).
Bobylev's calculations from 2010 suggest that this star will pass about 2.20 parsecs (7.2 light-years) from the Sun in about 341 thousand years.[3]
