Find Ursa Major, the "big dipper". Follow the lines of the two "bowl" stars Merak and Dubhe out from the lip of the bowl. Go seven times the distance between the stars, and you will see one star which is not particularly bright, but is brighter than the other stars around it. This is Polaris, the "North Pole" star.

To check your work, follow the line from the dipper to Polaris an equal distance across the sky. You should be in the middle of a giant crooked "W" of stars; this is the "Chair of Cassiopeia".

Strictly speaking, Ursa Major does not circle Polaris at all. The stars in the sky are "fixed", and do not move around. (This isn't exactly true; every star has its own "proper motion" across the heavens, but the motion is only observable on a scale of several CENTURIES. We don't live long enough to notice.)

But because the Earth is spinning, it APPEARS as if all the stars are moving - except one. Polaris, by an amazing coincidence, happens to be almost above the North Pole, and so all the other stars appear to rotate around Polaris, once per day.

Yes, this is generally how people find the north star (or pole star), since it is not especially bright or easy to find without the 'pointer' stars at the end of Ursa Major (or the plough (or the Big Dipper)).

If you locate the two stars at the end of this constellation you can then locate the pole start and find north. The constellation looks like a big saucepan, find the two stars opposite the `handle` then imagine a straight line leading through both of these stars and carry on another 4 or so times the length of the length between the two.

Ursa Major is a rather large constellation, covering a good-size patch of sky.

(Its seven brightest stars, forming the "Big Dipper" asterism, are only a part

of the constellation.) The sources we consulted give the declination as 55° .

Wherever that point is in the constellation, here's where you need to look

to see it:

-- Face north.

-- The point is somewhere between 35° left and 35° right of straight-ahead,

depending on the date and the time of night.

-- Its altitude above the horizon depends on your latitude.

-- If your latitude is 55° or more North, the point is always up, and never sets.

-- If you're on the equator, the point rises 35° east of north, and sets 35° west of north

12 hours later.

-- If your latitude is 35° or more South, then the point is always below your horizon.

The locations of the constellations change constantly, so there is no single answer. Ursa Major is visible all year round, normally high overhead.

Once every day, like any other star or constellation. More accurately, once every 23h56m. That is how many times it goes across the sky.

Not quite. Only if you live in the Northern Hemisphere will you be able to see them at all times.

What constellation is used to determine earth's north?

The constellation Ursa Minor contains the star Polaris, which is the pole star.Two stars in Ursa Major, Merak and Dubhe, form a pair line that points to Polaris. They are the stars on the edge of the "Big Dipper."


What do all circumpolar constellations have in common?

Northern circumpolar constellations revolve around the north celestial pole in a counterclockwise manner. They never seem to rise or set, in regards to the horizon. Every 24 hours they seem to complete a revolution around Polaris, the North Star. Because the Earth is a sphere, the number of circumpolar constellations that one sees depends on one's location from the North Pole. At the North Pole, every constellation in the night sky is circumpolar. Below the equator, one cannot see a single circumpolar constellation. These are the common circumpolar constellations of 40-50 degrees N latitude: Ursa Major Ursa Minor Cassiopeia Cepheus Draco


Does Jupiter revolve counterclockwise around the sun?

Viewed from the north, yes, viewed from the south, No. All the planets revolve counterclockwise as seen from the Sun's North Pole.


Which direction do all planets revolve?

All planets in our Solar System, viewed from above our North Pole, revolve around the Sun in an anti clockwise direction.


Why do constellations appear to revolve around the Pole star?

This is because the Pole Star (i.e. Polaris, in the Northern hemisphere) is within a degree of the Earth's centre of rotation. That is, the north pole is in line with this particular star. Thus, as the Earth rotates, Polaris does not appear to move in the sky, and the rest of the stars appear to revolve around it.

Is pole star located in Ursa major?

No. Ursa Major is often used as a way to find it, as part of it points towards it, but it is not actually in Ursa Major. It is in fact in Ursa Minor.


Is pole star is located by Ursa major constellation?

Yes. Pole Star is located by Ursa Major. On a clear moonless sky during summer at 9.00 p.m. at the northern part of sky you can see Ursa Major. Imagine a straight line that passess through these stars and extend this line towards the northern side to a star that is not too bright. This is a Pole Star. This star does not move at all. Ursa Major moves east to west of this Pole Star.


Which constellation is used to identify the pole star?

the constellation 'Ursa major' is used to identify the pole star


What are 5 circumpolar constellations?

The five circumpolar constellations are Ursa Major, Ursa Minor, Draco,Cassiopeia, and Cepheus. Each are constellations in the Northern Hemisphere that circle the pole star Polaris.


What is the constellation that guides us to the pole star?

Ursa Major, which some people refer to as the great bear or the big dipper.


Is the North star the same as Polaris?

Yes, Polaris in Ursa Minor is the "North Star" located using the stars of the Big Dipper (Ursa Major). It is currently the closest bright star to the celestial pole, i.e. the point directly above the Earth's North Pole. The pole star for the South Pole is currently Sigma Octantis in the constellation Octans.


Which costellation contains the North Star?

Ursa Minor. Currently. (Which star is "the north star" changes very slowly because the Earth "wobbles".) In about 10,000 years the north star will be Vega, which is in the constellation Lyra. The north celestial pole can also point to the locations within the constellations Draco, Cygnus, and Hercules over its 26,000 year long cycle.


Where the pole star is found?

Ursa minor constellation


What is the difference between Ursa Minor and Ursa Major?

Ursa major Ursa major is the third largest constellation and is also known as the great Barth big dipper, or the plough. it is visible in the northern hemisphere almost throughout the year. it has mythological significance throughout the world. the constellation consist of seven stars. Ursa Minor Also known as the little dipper, this constellation also consist of seven stars and the star at the end of the dipper handle is Polaris, commonly known as the pole star. It is not easy to spot this constellation since it is not so bright.


What are some well known constellations?

Some well known constellations are Ursa Minor (little dipper), and Ursa Major (big dipper). Ursa minor includes the North star, or Polaris. Polaris can tell you the relative location of the North pole. Orion's Belt is well known, but not all the stars in him are.
