What do Polaris and Procyon have in common?
Polaris is the brightest star in the constellation Ursa minor and Procyon is the brightest star in the constellation canis minor but the brightness of Procyon is not due to it's intense luminosity but it's closeness to the sun, at a distance of 11.46 light years, but both stars are bright
What is the life cycle of polaris?
Polaris is a type of star known as a yellow supergiant. It has likely already passed the midpoint of its life cycle and is currently fusing helium in its core. In the future, it will eventually exhaust its fuel and undergo a supernova explosion, which will mark the end of its life cycle.
What is the movement of polaris with change of latitude?
Polaris' 'elevation' ... the angle between it and your northern horizon ... is roughly equal to your
north latitude.
When you are . . .
. . . on the equator (zero latitude), Polaris is on your horizon;
. . . in Salem Oregon, Minneapolis, Grenoble France, Torino Italy, Ploiesti Romania, Jixi China,
Wakkania Japan, etc. (45 degrees north latitude), Polaris is 45 degrees above your northern horizon;
. . . at the north pole (90 degrees north latitude), Polaris is directly overhead;
. . . south of the equator, Polaris is due north of you but below the horizon.
When does polaris rise at night When does polaris set?
Because it is in line with Earth's axis of rotation, Polaris never rises or sets. It is always in the same place in the sky from any given location in the northern hemisphere.
How much does Polaris move in a one hour period of time?
Not enough that you would notice with the naked eye. It actually moves in a small circle over the course of 24 hours.
How much does a magnum Polaris weigh?
the Magnum 6x6 weighs 850 pounds. the 4x4 should weigh about 100/200 less
When can polaris be seen even in the day?
Polaris, also known as the North Star, can be seen during the day under specific conditions, such as when the sky is exceptionally clear and the sun is low on the horizon. This is typically around sunrise or sunset when the brightness of the sun is less intense. However, due to its brightness and position, it's often difficult to spot during daylight hours. Generally, viewing Polaris is best done at night when it is fully visible against the dark sky.
What month can Polaris be seen?
In the northern hemisphere Polaris can be seen in any month of the year.
What is the density of polaris?
Alpha Ursae Minoris (Polaris, North Star, Northern Star, Pole Star or Lodestar) is the brightest star in the constellation Ursa Minor.
It is actually a triple star system, that seems to us, as observed from Earth as a single star.
So it is impossible to give it's density.
an arora is when high charged paritcles come from some where lets say the sun they go from 900 to 10,000 miles per hour and collide into the atmaspher to make the glowing areas at the north pole and the south pole
The constellation that contains the pointer stars used to locate Polaris the North Star?
Ursa Major/The Great Bear/The Plough/The Big Dipper/The Drinking Gourd.
What is th approximate altitude of Polaris from uticaNew York?
The altitude of Polaris, also known as the North Star, is approximately equal to the observer's latitude. In Utica, New York, which is situated at about 43.1 degrees North latitude, Polaris would be observed at an altitude of roughly 43 degrees above the northern horizon. This means that if you are standing in Utica and looking north, Polaris would appear about 43 degrees up from the horizon.
What is the big dipper position in polaris?
It is the last star at the tip of the handle of the Little Dipper. The Big Dipper's first two bowl stars (often called the pointer stars) point towards Polaris, but Polaris is not in the Big Dipper.

Why does the pole star not seem to move?
Because they are located straight up from the point of the sky under them. The Earth rotates around this area, so the star in this area is more-or-less stationary.
If you stand under a balloon at a party and turn round and round while looking at it, then relative to your nose (which you might regard as fixed on you) the balloon goes round, but stays above you. Other balloons go around you.
The earth spins on its axis. The pole star is almost exactly above (ie pointed to by) this axis. So most stars appear to go round and round, but the pole star stays where it is. It actually does appear to do a very small circle because it is not precisely pointed to by the axis.
Because it lays on an imaginary line that extends from the axis that we rotate on.
You can simulate this in an experiment within you house or building. All you need is a video camera (or anythig that can record video, like a phone or ipod nano) and someplace with a bunch of lights or other objects on the ceiling or floor.
Take the video camera and look up at the ceiling (or down at the floor) and pick one light to focus on. While standing directly under that light and looking up at it, slowly spin in a circle while continually looking at that light. Hopefully there are other things on the ceiling that also appear in the frame of the movie, like other lights, or that dent that you made when you were rough housing with your friend and a baseball.
After about 30 seconds and several rotations (you don't need to rotate very fast at all), watch the video. You'll see that the light you were focusing on does not move, while all other objects in the sky appear to rotate around that light.
Compared to the Earth, you are the Earth and that light is the pole star.
2nd Answer:
Good answer! . . . . In actual fact, the Pole star, or Polaris, is changing its observed position relative to Earth, but for our lifetimes Polaris does lie (temporarily) on the extended Earth's axis. All the stars are moving relative to Earth, and in several more thousands of years, we may no longer recognize, for example, the Big Dipper and Little Dipper.
Polaris has also been observed by astronomers as moving relative to Earth. Thousands of years ago, Polaris and the other constellations were not where they are now. In thousands of more years, they, along with Polaris, will have moved on in their slow creep across the sky to new places.
pole star appears stationery in the sky and all other constellations appear to revolve around it. It points to geographic north direction and is very useful for sailors in finding directions at night.
There is no apparent movement of the pole star because they are the position points of the north and south pole
Polaris is a multiple star system - comprising of at least 5 stars.
The main star, Alpha Ursae Minoris has a temperature of about 7,200oK
