Pole of inaccessibility to reach this false northern pole of inaccessibility was made by Sir Hubert Wilkins, who flew by aircraft in 1927. In 1941, the first Soviet expedition using an airplane landed 350 kilometers north of the false northern pole, thus actually becoming the first expedition to reach the real pole. Ignoring Soviet results, Sir Wally Herbert claimed to be the first to reach what was then considered to be the northern pole of inaccessibility on foot, arriving by dogsled in 1968. Explorer Jim McNeill claimed in 2006 that Herbert did not quite make the pole, and launched his own unsuccessful attempt
Pole star takes about 25,770 years to complete a cycle. Polaris' mean position (taking account of precession and proper motion) will reach a maximum declination of +89°32'23", which translates to 1657" (or 0.4603°) from the celestial north pole, in February 2102. Its maximum apparent declination (taking account of nutation and aberration) will be +89°32'50.62", which is 1629" (or 0.4526°) from the celestial north pole, on 24 March 2100. Precession will next point the north celestial pole at stars in the northern constellation Cepheus. The pole will drift to space equidistant between Polaris and Gamma Cephei ("Errai") by 3000 AD, with Errai reaching
