Dubhe as a pole star?
Currently, the article states that Dubhe is the northern pole star for 5100 BC and 20500 AD. During these points in the Earth's axial precession, Dubhe's declination is less than 60 degrees. On the other hand, Alkaid, which is brighter than Dubhe, will have a declination of over 75 degrees. Though neither is as ideal as Polaris is currently (over 89 degrees and nearly as bright), wouldn't Alkaid be a better choice? --220.127.116.11 (talk) 16:56, 4 November 2009 (UTC)
I agree that Dubhe should not be considered to be a pole star, and recommend that the text stating that it was and will be be removed ASAP. For reference, take a look at http://en.wikipedia.org/wiki/File:Precession_N.gif, for example. The precession circle comes nowhere near the Big Dipper. Doesper (talk) 17:16, 4 December 2009 (UTC)
