Polaris is not exact, but very, very close ... closer than
you can read with a moderately good compass.
Unfortunately, if you're south of the equator, you can
never see Polaris in the sky, so it's not helpful to you.
Standing on the equator, you would not see any circumpolar stars. Circumpolar stars are those that never dip below the horizon, and they can only be seen from latitudes above a certain threshold, typically around 25 degrees (North or South) or higher. The closer you are to the poles, the more circumpolar stars you can see.
When in the northern hemisphere, looking north toward the celestial "axis" or North Star (aka Polaris), stars acan be oberserved to move all directions. To the south of Polaris (looking "above" it), the stars and other things move East to West across the sky. To the north of Polaris (looking "below" it), the stars and other things move West to East across the sky. Both are true for short distances, because in fact, the direction it moves is actually in a smaller and smaller circle the closer the star appears to be to Polaris. With a camera that can take long exposures (10-20 minutes or even hours) this circular motion can easily be seen.
Draco can be seen all year around, but the best time to spot this constellation is during the month of July. If you are looking north during the summer months, Draco is facing upright, but as the year goes on it slowly flips upside down. You can see Draco year-round in the northern hemisphere. The best viewing for Draco is during July at 80o above the horizon line while looking North.
At any time of any clear night, the North Star is visible from anywhere in Minnesota. In fact, it's visible at any time of any clear night from anywhere in the USA, as long as there isn't a building in the way.
From the Earth's North Pole, you can see the northern stars, the northern lights (aurora borealis), and the sun moving in a circular path around the horizon during the summer months. The North Star, Polaris, is also visible at the center of this rotation.
What we see as the north star, or Polaris or the pole star, is a binary system consisting of two stars. However, neither of these stars are the brightest stars. There are many stars that are much brighter as we see them.
The stars over the North Pole
the stars
Yes, when we observe stars, we are looking at the past because the light from stars takes time to travel to Earth, so we see them as they were in the past.
If you were standing on the North Pole, you would be able to see all the circumpolar stars in the sky. Circumpolar stars are the stars that never set and orbit around the celestial pole. At the North Pole, they would constantly circle around Polaris, the North Star, without dipping below the horizon.
If you're located anywhere in the northern Hemisphere, then you can see all the stars that are within (your north latitude) of the North Celestial Pole at any time on any clear night of the year. As seen from your location, they never set.
At the North Pole, and at the South Pole.
As many as the stars.
Because the speed of light is finite (around 186,000 miles per second) and the stars are so distant, it takes a long time for the light to reach the telescope from the stars - at least 4.2 years. Many objects are millions of light years distant, meaning that what we see in the sky is from the distant past.
find the big dipper. its bottom of the cup will point to the north star. look straight up. draw an imaginary line in the sky from where your looking at to the north star. that is north.
Some northern hemisphere stars can be seen from the southern hemisphere depending on the latitude. For example, Polaris, the North Star, cannot be seen from the southern hemisphere. However, stars like Vega and Capella can be visible from both hemispheres.
No. As you have no doubt noticed, you cannot see the stars during the day.
