~500 answered questions
Parent Category: Stars
Polaris is Earth's current northern pole star, and thus is commonly referred to as the North Star. Historically, Polaris was used by sailors and navigators to determine their current latitude while crossing oceans. Please place all questions about Polaris, the brightest star in the constellation Ursa Minor, into this category.
Polaris (also known as the North Star, Northern Star or Pole Star) is the brightest star in the constellation Ursa Minor. It is actually a star system, consisting of a main star and five other smaller companions. The main star (α UMi A) has a spectral type of F7 meaning it is still on the main seq…

Polaris is at its upper culmination once every 23hours 56minutes 4seconds. (rounded) It happens when the local celestial meridian is equal to Polaris' right ascension, and that's a different time every day of the year. Probably your best source would be the staff of a local planetarium, or a loca…

Polaris is almost exactly above the North Pole so other stars appear to rotate around it as the Earth rotates, around the pole, UNDER Polaris.Stars, except the trivial case of OUR sun, are immobile. The Earth rotates directly under Polaris, around the polar axis through both North and South poles.

They have move, but not necessarily by much. The stars that are visible to the naked eye are generally within a few hundred light years of Earth, and some are only a few light years away. So you see those stars as they were, at most, a few hundred years ago, which, to a star, is a very short time. D…

As the night progresses, Polaris appears to stand still, and all the other stars turn around it in a counterclockwise direction.

Only places in the northern hemisphere can see the Pole Star Polaris. Anyplace south of the equator, this star is below the horizon. In fact, it's very difficult to see ANY star that is within a degree or two of the horizon, so very few people south of 2 degrees north latitude have ever seen it.

Polaris is called the north star because it is directly above Earth's north pole. So, if you find Polaris in the sky, that direction is north. Actually, Polaris is very close, but not exactly in line with the north pole. It is off by about 0.7 degrees.
