At which location is the altitude of Polaris approximately 43?
Notice that that for a spot at latitude θ the view of the sky makes the same angle θ with the north pole. Since Polaris is at an extension of the north pole this is the angle at which Polaris lies above the horizon. Therefore for Polaris to be 43o above the horizon we must be standing at a latitude of 43o .
At which location is the altitude of Polaris 42?
At which location is the altitude of Polaris approximately 42 degrees? Elmira, cause the altitude of Polaris is 42 and alt of Polaris equals latitude of observer, and only Elmira is near the 42 degree latitude line.
What is the highest altitude that Polaris can be in NYS?
Since Polaris is at an extension of the north pole, this is the angle at which Polaris lies above the horizon. Therefore, for Polaris to be 43o above the horizon, we must be standing at a latitude of 43o .
Which New York State location would Polaris be observed to have an altitude closest to 43 above the northern horizon?
The correct answer is Utica. Utica is the New York State location that is closest to 43 o ^o o above the Northern horizon.
What is the altitude of Polaris above the northern horizon?
0 degrees Polaris is the North Star, located above the North Pole along the north celestial pole. When viewed from the equator it lies on the northern horizon (at an altitude of 0 degrees), and when viewed from the North Pole it lies directly overhead (at an altitude of 90 degrees).
At which latitude will Polaris be overhead?
At what latitude will Polaris be overhead? 90 degrees north.
How do you find the altitude of a Polaris map?
Align the 0° edge of the compass with the horizon. Keeping the 0° edge flat against the horizon, lift one arm of the compass until it points directly at Polaris. Read off the angle. This is the altitude of Polaris from your location on Earth.
Where is the altitude of Polaris the maximum?
Polaris is directly overhead at the North Pole (90° of latitude); in other words, the angle between Polaris and the horizon at the North Pole is 90°. This angle is called “the altitude” of Polaris.
At which map location does Polaris appear the highest in the nighttime sky?
As you travel northward, Polaris climbs higher in the sky. If you go as far north as the North Pole, you'll see Polaris directly overhead. As you travel south, Polaris drops closer to the northern horizon. If you get as far as the equator, Polaris sinks to the horizon.
What is the height of Polaris above the horizon?
(30 degrees latitude)– Polaris is located 30 degrees above the northern horizon. This trend continues until the traveler reaches the geographic (not magnetic) North Pole. At this point (90 degrees latitude), Polaris is 90 degrees above the northern horizon and appears directly overhead.
What is the latitude of Polaris?
90° In other words, for observers in the Arctic region, the latitude of the Polaris is 90°, and for the observer in the equator, the region is 0°.
How high in the sky is Polaris?
(30 degrees latitude)– Polaris is located 30 degrees above the northern horizon. This trend continues until the traveler reaches the geographic (not magnetic) North Pole. At this point (90 degrees latitude), Polaris is 90 degrees above the northern horizon and appears directly overhead.
Where is Polaris in the sky?
Polaris is located quite close to the point in the sky where the north rotational axis points – a spot called the north celestial pole. As our planet rotates through the night, the stars around the pole appear to rotate around the sky. Over the hours, these stars each sweep out a circle around the celestial pole.
What latitude is Polaris?
90° This device allowed him to measure the “altitude” of Polaris or the North Star. Polaris is directly overhead at the North Pole (90° of latitude); in other words, the angle between Polaris and the horizon at the North Pole is 90°. This angle is called “the altitude” of Polaris.
Why is Polaris always north?
Polaris, the North Star, appears stationary in the sky because it is positioned close to the line of Earth's axis projected into space. As such, it is the only bright star whose position relative to a rotating Earth does not change. All other stars appear to move opposite to the Earth's rotation beneath them.
What is the altitude of Polaris above the northern horizon for observer A?
0 degrees Polaris is the North Star, located above the North Pole along the north celestial pole. When viewed from the equator it lies on the northern horizon (at an altitude of 0 degrees), and when viewed from the North Pole it lies directly overhead (at an altitude of 90 degrees).
What degree is Polaris?
Remember that the altitude of Polaris is 0 degrees if you are observing from the equator (0 degrees latitude) and 90 degrees if you are observing from the north pole (latitude 90 degrees), and it is also true for intermediate latitudes. So, knowing the altitude of Polaris lets you know your latitude on Earth.
Is Polaris always north?
We call that star the "North Star" since it sits in the direction that the spin axis from the northern hemisphere of Earth points. At present, the star known as Polaris is the North Star. However, Polaris has not always been the North Star and will not always be the North Star.
How long will Polaris be the North Star?
After 2102, the NCP will slowly move away from Polaris and within 2,000 years will pass close to Errai, a star within Cepheus the King.
How do you find Polaris?
Want to find it? You can use the famous Big Dipper asterism to locate Polaris. Notice that a line from the two outermost stars in the bowl of the Big Dipper points to Polaris. And notice that Polaris marks the tip of the handle of the Little Dipper.
Will North Star ever burn out?
The North Star, a celestial beacon to navigators for centuries, may be slowly shrinking, according to a new analysis of more than 160 years of observations. The data suggest that the familiar fixture in the northern sky is shedding an Earth's mass worth of gas each year.
How far off is Polaris from true north?
Only about 0.7 degree separates Polaris from the North Celestial Pole, the pivot point directly north of the Earth around which the stars circle daily. That distance amounts to less than the apparent width of 1.5 full moons, making Polaris a truly remarkable fixed point in the night sky.
How high above the northern horizon is Polaris the North Star?
(30 degrees latitude)– Polaris is located 30 degrees above the northern horizon.
How high above the horizon is Polaris in?
90 degrees Polaris is the North Star, located above the North Pole along the north celestial pole. When viewed from the equator it lies on the northern horizon (at an altitude of 0 degrees), and when viewed from the North Pole it lies directly overhead (at an altitude of 90 degrees).
What will be the North Star in 14000 years?
Sometimes there's no bright star near the celestial pole, as is the case in the Southern Hemisphere at present. About 14,000 years ago, the celestial pole pointed toward the bright star Vega, and as it sweeps out its slow circle, it will again point to Vega in about 12,000 years.
Will Polaris be North Star again?
Because of precession, different stars will serve as north stars and the constellations arrayed along the ecliptic (zodiac) will gradually change positions. Their move about one degree every 73 years. Polaris will remain the North Star throughout the rest of our lives and for a few centuries later.
How long will Polaris live?
Because of precession, different stars will serve as north stars and the constellations arrayed along the ecliptic (zodiac) will gradually change positions. Their move about one degree every 73 years. Polaris will remain the North Star throughout the rest of our lives and for a few centuries later.
How old is Polaris?
70 million years Polaris is easily visible to the unaided eye, but not exceptionally bright. It is the brightest star in the constellation Ursa Minor, but only the 48th brightest star in the sky….Alpha Ursae Minoris Ab.

Where is Polaris right now?
Polaris, known as the North Star, sits more or less directly above Earth's north pole along our planet's rotational axis. This is the imaginary line that extends through the planet and out of the north and south poles.
What is the altitude of Polaris at the North Pole?
90 degrees Remember that the altitude of Polaris is 0 degrees if you are observing from the equator (0 degrees latitude) and 90 degrees if you are observing from the north pole (latitude 90 degrees), and it is also true for intermediate latitudes.
