|Description||The constellation of Ursa Minor, though not very brilliant, is important since it contains the North Pole, indicated by Polaris, the principal star of the constellation.
Polaris is a yellow supergiant which is about 600 light-years away: it is not exactly at the North Pole, but it is at a distance of less than one degree; because of the precession, however, it is approaching the Pole (it will return to get further after 2100). Polaris is a variable star, which oscillates between magnitude 2,1 and 2,2 with a period of about 4 days, and besides it is a double star, considering that it has a companion of ninth magnitude.
|According to Aratus, the constellation represents one of the two nymphs who raised the new-born Zeus: in particular it is Ida, while the other, Adrastea, is identified in Ursa Maior.|
