    The Martian north celestial pole resides in the constellation Cygnus- near the border of Cepheus.
    Unfortunately, the stars nearest the pole are too faint to be useful. The closet is approximately a half-degree away and is barely visible to the naked eye. The pole is close to the halfway point between Deneb in Cygnus and Alderamin in Cepheus-- the brightest stars in their respective constellations.

    While the axial tilts are similar in degree, Mars is tilted in a different direction. Earth is tilted so that its axis points toward Polaris. Mars' points toward Cygnus/Cepheus.

    Also, it is bad form to completely edit your posts to change their meaning. It creates confusion and makes it hard to figure out what's going on. Just add a new post that contains what you want to say.
