Alderamin (Alpha Cephei)
The brightest star in the constellation Cepheus and a subgiant A star.
Alderamin is a white A7V main sequence star. From the spectral type a temperature of about 8100 K may be inferred. The star would be probably about 1.5 times larger in diameter than the sun and maybe 9 times more luminous.

Like Alderamin, Errai periodically takes a turn as the Pole Star in Earth's Northern Hemisphere, which will happen again in about 2,500 years. The system exhibits an annual proper motion of 0.

[2321] alpha Cephei or Alderamin ("the right shoulder" or "the right arm") is the brightest star in Cepheus. It is an A-type subgiant on its way to becoming a red giant, located near the precessional path of the north celestial pole.
Alpha Cephei is known as Alderamin ("The Right Shoulder"). In another 5500 years this will become the Pole Star.
Beta Cephei is called Alfirk ("The Herd"). This is a visual binary as well as a variable (see below).
Named stars: Alpha Cep (Alderamin), Beta Cep (Alfirk), Gamma Cep (Errai/Arrai), Mu Cep (Granatstern)

Polaris is due to become an even more accurate pole star in the near future - the distance between Polaris and the pole will reach a minimum of just under 1/2° in the year 2100. After that, Alderamin in Cepheus will be the Pole Star around 7500 AD, ...
