What is the approximate altitude of Polaris at New York City?

On April 21, the altitude of Polaris , as viewed from a location in New York State, was measured as 41.3°. What will the altitude of Polaris be when viewed one month later, on May 21, from the same location? A) Polaris rotates on its axis.

At which location is the altitude of Polaris approximately 42?

15. 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 possible altitude of Polaris?

At the Equator (0° of latitude ), the North Star is on the horizon, making an angle of 0°. For any point between the Equator and the North Pole, latitude is obtained simply by measuring the altitude of Polaris : at 30°N the star is 30° above the horizon, at 63°N, it is 63° above the horizon, and so on.

How do you determine the altitude of Polaris?

Point out that the North Star, Polaris , is directly above the North Pole. Ask the students to imagine that they are at the North Pole. Ask them where in the sky they would look for Polaris (straight up). Point out that the angle from the horizon to Polaris is called the altitude of Polaris .

Does Polaris have a long or short Star Trail?

Polaris actually lies just a short distance away from where Earth’s axis points. Earth’s axis points almost directly to Polaris , so this star is observed to show the least movement. The other stars appear to trace arcs of movement because of Earth’s spin on its axis.

What happens to the altitude of Polaris as you move west?

Answer Expert Verified. Polaris moves along with normal altitude a as it is located right above the axial pole north – so, 90ºN. The latitude of Mamaroneck and Chicago doesn’t vary by much so it can be considered ignorable.

What is the altitude of Polaris at the Tropic of Cancer?

23.5

What is the true shape of the earth?

The Earth is an irregularly shaped ellipsoid . While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid . However, even an ellipsoid does not adequately describe the Earth’s unique and ever-changing shape.

What happens to the altitude of Polaris as you travel northward?

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.

Where on earth will Polaris be directly overhead?

(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 .

How accurate is the North Star?

But the North Star does move. If you took its picture, you’d find that it makes its own little circle around the exact point of the north celestial pole every day. That’s because the North Star is really offset a little – by about three-quarters of a degree – from celestial north .

What is the lowest possible altitude of Polaris?

During a 25,800-year cycle, the position of Earth’s axis in space traces out a 46.88°-wide circle on the sky. In 12,600 years, Polaris will reach its lowest declination of 44.62°.

What does altitude mean?

As a general definition, altitude is a distance measurement, usually in the vertical or “up” direction, between a reference datum and a point or object. Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage.

Does the altitude and azimuth of a star ever change?

Since stars change their position with respect to your horizon throughout the night, their altitude – azimuth position changes . This system is fixed with respect to the stars so, unlike the altitude – azimuth system, a star’s position does not depend on the observer’s location or time.

What is the angle of the North Star?

At the North Pole (90° north latitude), Polaris is directly overhead at an angle of 90°. At the Equator (0° latitude), the star is sitting on the horizon with an angle of zero.
