What cause the north star to change between the stars vega polaris and thuban?
The Earth is like an enormous gyroscope, spinning in space. We think of gyroscopes as always pointing in the same direction, but all gyros wobble a little bit, with a motion called "precession". The Earth's precession causes the north pole to move VERY SLOWLY. The north pole of the Earth is currently pointed to the star Polaris, but it hasn't always been, and won't always be. The cycle is 25,800 years long.As the centuries pass, the Earth's precession will cause the north pole to slowly move away from Polaris, and in about 12,000 years will point somewhere near Vega. In another 14,000 years, the north pole will be pointed somewhere near Polaris again - except that Polaris itself is moving. In 26,000 years, Polaris will be about 5 degrees away from the pole.
What does steering by a star mean?
The stars move very very slowly from our perspective because they are so far away. Polaris, sometimes called the North Star, is and has been for millennia, located directly above the northern pole of the earth's axis, which means that if you are in the northern hemisphere and you need to know where north is to be able to steer a ship at sea, the North Star will give you that information. The Southern Cross performs a similar function in the Southern hemisphere. If you are sailing near the equator, the pole stars will be near the horizon and may be hard to see. However, if you know the constellations and particularly the signs of the zodiac, which are on the ecliptic, you should still be able to calculate your directions more or less.
What makes the north star polaris special?
It appears stationary in the night sky, due to the fact that it lined up almost directly over the North Pole. Because of this it can be used to find true north, which is a very useful thing when sailing at night and all other points of reference are gone, such as landmarks or the sun.
How many degrees above the horizon is the north star from longitude 39 degrees 53 ft and 49 inches north and latitude 76 degrees 9 ft 50 inches west at 5AM?
The "North Celestial Pole" of the sky is always due north of you, and at the same angle above your horizon as whatever your north latitude is. It doesn't move, and the north star is always within about 1/3 of a degree from that point. Your longitude makes no difference at all. And neither does the time of day. And feet and inches have no place in angle measure. And latitude is north or south and longitude is east or west.
Is 2012 reel?
yes if you are reading this save your self people have predictad it to be real it will strike in the north pole and move up east this is top secret but if you want to live tell every one
How will the constellations move across the sky if you are standing at the North Pole?
If you are standing at the North Pole, the constellations will appear to rotate counterclockwise around the North Star (Polaris). This is because the North Star is directly above the North Pole, and as the Earth rotates on its axis, the stars appear to move in circles around it.
Do stars at north pole move?
No, The stars themselves are not moving, but the Earth is rotating. This gives the appearance that the stars are revolving in circles around the pole in a counterclockwise direction
What must be your location if the stars move across the sky in circles cetered directly overhead?
Your location must be located on the Earth's axis, specifically at the North or South Pole. At these locations, the stars appear to move in circles around the celestial pole that is directly overhead.
Stars near the north celestial pole appear to move?
Stars near the north celestial pole appear to move in a counter-clockwise circle because of the Earth's rotation. This effect is known as the diurnal motion of stars due to the Earth's rotation on its axis. Polaris, the North Star, remains nearly stationary as other stars appear to revolve around it.
Do circumpolar stars move counterclockwise around the north celestial pole?
Yes, circumpolar stars appear to move counterclockwise around the north celestial pole due to the rotation of the Earth on its axis. This motion is known as diurnal motion and is responsible for the apparent daily movement of stars in the night sky.
How does a magnets North Pole behave when brought near another North Pole?
they move away
Why is polaris famous?
Polaris, also called the North Star, is just about in line with the north pole and so does not appear to move across the sky as other stars do.
Why does the pole star stay due north while the rest of the plow can be in all positions around the pole star?
The stars don't move, the Earth (and you) does. You're spinning (once a day) around a line drawn from the north pole to Polaris.
Why do all stars appear to move except the pole star?
All stars appear to move due to Earth's rotation, but the Pole Star, also known as Polaris, remains in a relatively fixed position in the sky because it is located almost directly above Earth's North Pole. This causes it to appear stationary as other stars appear to rotate around it.
Where on Earth so stars always circle the zenith and never rise and set?
The stars always circle the zenith, or the point directly overhead, at the North Pole. This phenomenon occurs due to the Earth's rotation on its axis, which causes the stars to appear to move in a circular pattern above the North Pole without rising or setting.
Pole star how do you find diections?
The Pole Star, also known as Polaris, can help you find direction by locating the North. It is located very close to the north celestial pole, so it remains nearly stationary while other stars appear to move across the sky. By locating Polaris, you can determine which way is north, south, east, and west.
At the north pole do surface winds move north or south?
Surface winds at the North Pole generally move from the south towards the north, forming the Polar Easterlies. These winds are a result of the temperature difference between the cold polar regions and the warmer mid-latitudes.
