-3.64 is the absolute magnitude of Polaris.
If it's important to anybody, that's because it's a relatively bright star that always remains more or less in the same position, as seen by us.
It is useful because it is directly above Earth's north pole so if you were traveling north, you would know what to follow
Polaris, also known as Alpha Ursae Minoris, will become the North Star again in 27,800 AD. The cycle takes about 25,770 years to complete. Polaris is the current North Star. Polaris replaced Thuban around the first millennium BC. It will become closest to the celestial north pole around the...
Within 1/2 degree of 70N. Polaris is not EXACTLY above the North Pole; it is about 0.6 degrees from it.
Back in the old times in exploring through seas Navigators usePolaris to know where is north and to find out where they are justlike using constellations.
Above the northern horizon
It is at the tail end of the little dipper, which is part of Ursa Minor, the little bear.(:
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...
no. Polaris is not inside the southern cross.
If Polaris appears 60° above the northern horizon, then you are pretty near 60° north latitude. If you're on the equator ... 0° north latitude ... then Polaris is on the horizon ... 0° altitude. If you're at the north pole ... 90° north latitude ... then Polaris is over your head ... 90°...
No one discovered Polaris. It has been in the night sky since humans first walked the Earth.

No. Is located almost directly over the North pole.
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.
Polaris or Alpha Ursa Minoris is actually a multi star system of 3 to 5 known stars.Polaris A is a yellowish white giant or supergiant star approx 6 solar masses in mass.Polaris Aa is yellowish white dwarf star in close association with Polaris A (18.5 AU).Polaris B is a yellowish white star about 1...
Polaris just happens to be positioned almost (but not quite exactly!) above the North Pole. So if you are facing Polaris, you are facing almost exactly north. If you measure the altitude of Polaris as an angle above the horizon, you can read your latitude directly on your sextant. It isn't exact;...
the polaris is much larger than sun because polaris is a super giant star while sun is only a dwarf
First you need to find the asterism the "Big Dipper" or the "Plough". This is one of the easiest asterisms to find.The create a line from the 2 right most stars and keep following this line up. The next bright star on this line is Polaris.
Polaris is in Ursa Minor (Little Dipper).
Yes, you can see Polaris all year... it's the North Star.
More or less. Polaris is less than one degree from the north pole of the sky (i.e., the extension of Earth's axis). This situation changes over time: due to precession, the alignment of Earth's axis gradually changes.
Polaris is the north star, meaning it is always visible up in the sky if you live above the equator.
the waste of hades or the waste of Poseidon
Correct. Polaris is a star, not a planet.
Polaris, or North Star is a supergiant about six times as large as our Sun. Therefore the majority of stars will be smaller.
Axial tilt.spherical shape
No. Polaris is a system of three stars, all of which are larger than the sun.
Polaris is in the constellation Small Bear (Ursa Minor). I didn't check whether it actually is the brightest star in that constellation.
If the man is standing on 400 North, then he can see the polaris exactly at an angle of 400 in the north direction.
Polaris does have apparent movement, but it is slight. Now, the angular distance of Polaris to true north is less than 1 degree). So, the other stars appear to be rotating around Polaris as the earth rotates throught he night.However, the earth wobbles around its rotational axis, resulting in true...
Because the earth's north pole happens to point [very close] to Polaris.
Polaris is at declination 89.3 degrees north, so it is 0.7 degrees away from the north celestial pole. However, Earth's axis of rotation is not fixed; the Earth wobbles like a gyroscope, with a period of about 23,000 years.
Fairbanks, Arkansas is located at latitude 35.380935N, so Polaris is roughly 35.380935 degrees (plus or minus 0.73 degrees) above the horizon.
The angle of Polaris above the horizon is the same as the latitude from which you are trying to measure it. Hollywood Florida has a latitude of ~26 degrees, so Polaris is 26 degrees above the northern horizon.
Polaris is about 7.5 times larger than the Sun.
Polaris, also known as the north star or pole star.
Polaris always sits within about 1/2 degree from the point in the sky that's the same angle above the northern horizon as your latitude. For example, if you're standing at the north pole, the point is directly over your head, and if you're anywhere on the equator, the point is on the horizon...
No. In fact, Polaris is the dimmest of the 57 stars commonly used for celestial navigation. Except for the happy coincidence that Polaris perches almost precisely above the Earth's north pole, nobody would think anything about it. In fact, we're fortunate that the skies around the north pole are...
The two "pointer" stars at the lip edge of the Big Dipper are Merak and Dubhe. Follow the line between them and extend it about 7 times their separation; the only even vaguely bright star there is Polaris.
No, Venus is a planet in orbit around the sun as is Earth. Polaris is a star and thousands of light years away.
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...
Polaris' "elevation" ... its angle above your horizon ... is very close to the north latitude of the place where you're located when you see it. So, as your north latitide increases, the elevation of Polaris also increases. And as you travel south, the elevation of Polaris...
The North star will be 75 degrees above the horizon. Whatever degree you are at latitude, the North star will be the same degrees up. So at the north pole (90 degrees north), the star will be at the zenith (straight up). While at the equator (0 degrees north) the star will be at the horizon.
Like all stars, Polaris is made of mostly Hydrogen, but since polaris is a red giant it has a considerable ammount of Helium, as well as Carbon, Oxygen, and a number of other elements deep in it's core.
His location would be somewhere very near 40 degrees north latitude. That could be places in Portugal, Spain, Italy, Greece, Turkey, Armenia, Azerbaijan, Turkmenistan, Uzbekistan, Tajikistan, Kyrgyzstan, China, North Korea, Japan, California, Nevada, Utah, Colorado, Kansas, Missouri, Illinois...
Every star is pretty huge, compared to anything in our life experience. In size. Betelgeuse: Red giant. Diameter 1,180 solar radii. Aldebaran: Orange giant: 45 solar radii. Alpha Centauri - Which one? A, B or C. For A, yellow dwarf: 1.22 solar radii. Polaris: Which one? A, Ab, B , C or D? For A,...
the altitude of polaris is same as the latitude of your location assuming that you are in the northern hemisphere
Because Sirius is hotter and closer to Earth than Polaris.
the degree of polaris on the horizon is your latitude. Shows the curvature of the earth. When the degree of polaris is 1 degree greater, you move the some distance if you move another degree. Shows how everything is equally distant from the center.
Polaris is not a white dwarf. If it was you wouldn't be able to see it. Polaris is in fact a multiple star system, that just looks like one star. The brightest star is a bright giant with a spectral type of F7 - so it will appear as a yellow-white star.
No, Polaris is always in the same spot in the sky.
As long as the sun continues to shine with roughly the same energy output, the seasons won't change at all on account of precession of the earth's axis. The axis will still incline about 23.5 degrees from the perpendicular to the ecliptic plane, and the annual variation of solar angle at any...
Polaris is a not the brightest star in the sky, but that is because we are very far away from it. If you were to visit Polaris, you would find it would be even brighter than the Sun
They are both stars of the Milky Way Galaxy.
12 volts just like a car.
No. Polaris is only visible in the northern hemisphere, and the Polynesians did most of their navigation in the southern hemisphere, or so close to the equator that Polaris wouldn't be usable.
Most stars move so slowly that it would take several lifetimes for anyone to notice a difference. The stars around Polaris don't move any more than the others. Because the Earth spins on its axis, while we ride along on it, there is a perception that the stars move around Polaris - but this is a...
to detect Polaris also known as "north star" you first will have to be in the northern hemisphere of the globe if you are south of the equator you will not be able to see Polaris. second you find the big dipper at the very end of the cup part not near the handle there will be the start of the little...
Imagine a line that goes in at the south pole, through the earth, and out of the north pole. Then imagine the earth spinning about this line or axis, as a bead might spin on some string - this is how the earth rotates, one revolution a day. Imagine the line coming out of the north pole, and continue...
because it is the center of the universe two camels in a tiny car
It's just about at the north celestial pole... right now..
However, it's about as close to the celestial pole as it ever gets, and either already is or soon will start drifting away (very slowly)..
Polaris is only directly overheat if you are at the north pole.
Your observations appear to be suffering from aliasing due to undersampling. The Big Dipper ... and practically everything else in the sky ... appears to make a complete rotation around Polaris every day . The reason is that the observer ... you ... are standing on a platform that turns ...
Alpha Centauri: NoAntares: NoPolaris: YesBetelgeuse: Yes
The last star at the tail end of the little dipper(ursa minor) or the two top stars in line of the big dipper(ursa major) that point to first star polaris.
If you're anywhere on the earth's northern Hemisphere, then yes. Polaris appears to essentially not move at all during the night, and it continues not moving during the rest of the 24 hours, even when daylight arrives. You simply can't see it when the sun is up and you're surrounded by air. ...
This is the order from smallest stars to the biggest stars: Alpha Centauri, Procyon, Vega, Pollux, Polaris, and Deneb. These are the size(diameter) of them; though the size of the stars are not 100% accurate so they are likely to be predicted. Alpha Centauri is 1,527,000 Procyon is 2,652,000 Vega is...
Anywhere in the northern hemisphere.
Polaris has a luminosity of 2,200 solar luminosities.
Polaris is the north star, being possitioned directly above the north pole it doesn't move from it's spot in the nigth sky, this can be used to both tell direction and time at nigth without a compass or a watch.
Polaris has been there all along. The ancient Phoenician and Chinese astronomers knew about it, and the Phoenicians used for navigation. (Not that it did them all that much good, since ancient ships were difficult to keep on track; the ships went where the wind did.)

Polaris is the closest of the three stars.
Polaris is the North Star that the fishing or shrimping vessels use in navigation. eD.
another name for the north star is polaris
1) Polaris moves, just as all "fixed stars" do. 2) The Earth's axis precesses (wobbles in a circle) like any gyroscope (spinning object) over a period of about 25000 years; thus celestial north changes.
Polaris is more commonly known as the North Star or Pole Star because its position in the northern night sky almost exactly marks the Earth's geographic north pole.
