HR906 is a variable and double giant star of spectral class A7 in the constellation of Cepheus.

HR906 visual magnitude is 5.95. Because of its faintness, HR906 is visible to the naked eye only from locations with very dark skies, while it is not visible at all from skies affected by light pollution.
