Polaris

Polaris is Earth's current northern pole star, and thus is commonly referred to as the North Star. Historically, Polaris was used by sailors and navigators to determine their current latitude while crossing oceans. Please place all questions about Polaris, the brightest star in the constellation Ursa Minor, into this category.

What is closer to earth polaris or the moon?

The Moon is closer to Earth than Polaris. The Moon is our planet's natural satellite, orbiting at an average distance of about 384,400 km, while Polaris is a star located about 433 light-years away from Earth, making it much farther.

Determine the distance between Polaris and Earth in meters?

The distance between Polaris (North Star) and Earth is approximately 433 light-years, which is about 4.086 × 10^18 meters. This distance is constantly changing due to the movement of both Earth and the star.

What galaxy is polaris in?

Polaris, also known as the North Star, is located in our Milky Way galaxy. It is a prominent star in the constellation Ursa Minor and is widely recognized for its position near the celestial north pole, making it a useful navigational aid.

How old is polaris?

As with a lot of astronomical objects, defining their age is just not possible.

Because of it's type, it could be about 4 billion years old, and has about another 2 billion years left, but these are just guesses based on it's spectral type.

Is Polaris almost at plus 90 degrees?

Yes, Polaris is very close to being at the celestial pole, which is approximately plus 90 degrees declination in the sky. It is used as a navigational aid for celestial navigation and is a good guide for finding true north in the Northern Hemisphere.

Hattiesburg mississippi lies about 31 degrees north where is polaris at 9pm on January 1st?

Polaris is within 1/2 of one degree of the North Celestial Pole. If Hattiesburg, MS is at 31 degrees north, then the elevation of Polaris is about 59 degrees - ALL the time.

Within 1/2 degree, at any rate.

What are all the names of Polaris?

Polaris and the North Star are the only two names I know.

At which New york state location is the altitude of polaris closest to forty five degrees?

Just north of Massena, NY, there is a park called St. Lawrence State Park. Barnhart Island is part of that park. If you cross onto Barnhard Island and head for the beach, the south end of the parking lot is exactly at 45 degrees north.

The question, however, is where is the altitude of the star Polaris closest to 45 degrees. Polaris is not PRECISELY above the North Pole; it is actually about 0.6 degrees away. So depending on the time of day, Polaris could be a 45 degrees elevation anywhere within about 30 miles of the New York/Canada border.

How can you find Polaris in th night sky?

Polaris is a close neighbor of our solar system, located only about 430 light years away, in

a direction very close to the direction in which the earth's north pole is currently pointing.

It can be seen in the sky directly north of any observer, at an angle above the northern

horizon equal to the observer's north latitude.

What does polaris rmk mean?

"RMK" stands for "Rocky Mountain King," which is a popular line of snowmobiles produced by Polaris. These snowmobiles are designed for rough, mountainous terrain with features focused on performance, maneuverability, and durability. The name "Polaris RMK" signifies the snowmobile's ability to conquer challenging mountain landscapes.

When is Polaris directly overhead?

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 directly north of you.

What is Polaris another name for what heavenly body?

Polaris is in fact a multiple star system, consisting of three main stars and two companions.

The main star Polaris A (α UMi A) is a six solar mass bright giant with a spectral class of F7, meaning it has a colour of yellow -> yellow white.

It has a radius about 30 times that of our own Sun and has a temperature of about 7,200.

Polaris is about 430 light years from us.

Grease points on 2004 Polaris Sportsman 500 ATP HO?

On a 2004 Polaris Sportsman 500 ATP HO, you should grease the front and rear suspension components, steering components, and drive shafts. Use a high-quality lithium grease and follow the recommended intervals in the owner's manual for regular maintenance. Make sure to clean and inspect the components before greasing to ensure proper lubrication.

What is the altitude of Polaris in Albany?

Since Polaris is (more or less) directly over the celestial pole, for any point in the northern hemisiphere it will be a number of degrees above the (theoretical) horizon equivalent to the latitude of the location you're observing it from. Its altitude above the actual horizon may be different, due the fact that the Earth isn't a perfect sphere.

The light from Sirius is 24.2 times more intense than light from Polaris What is the magnitude difference?

Apparent magnitude of Sirius = -1.44

Apparent magnitude of Polaris = 1.97

To the Earthbound observer, Sirius appears (1.44 + 1.97) = 3.41 magnitudes

brighter than Polaris.

1 magnitude = (100)1/6 times as bright

3.41 magnitudes = (100)3.41/6 = 13.7 times as bright as Polaris

Why is polaris important?

Polaris is important because it is also known as the North Star, making it a reliable navigational tool for finding direction, especially for travelers in the Northern Hemisphere. Its position is almost directly aligned with the Earth's axis, allowing it to remain relatively fixed in the sky throughout the night as other stars appear to move.

Did the Polynesian navigators find their way by observing the star Polaris?

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.

What does polaris point to?

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.

Several thousand years the polaris in the sky has changed due to?

The position of Polaris in the sky has shifted over thousands of years due to the Earth's axial precession, which is a slow change in the orientation of Earth's rotational axis. This natural phenomenon causes the apparent motion of stars in the sky to change over long periods of time. Over millennia, Polaris will no longer remain the North Star as other stars gradually take its place due to this celestial process.

What is polaris second name?

Polaris is a name given to whichever star is currently nearest to the celestial north pole. The position moves from one star to another. By the end of the 21st Century the celestial pole will move away from the current Polaris.


In English, another name for Polaris is the North star.

Does Polaris reflect light?

Polaris (North Star or Pole Star) has an apparent magnitude of +1.97 (Variable)

When you look up at the stars are they really present at that place or are they somewhere else as the light from them reaches us in many light years?

They have move, but not necessarily by much. The stars that are visible to the naked eye are generally within a few hundred light years of Earth, and some are only a few light years away. So you see those stars as they were, at most, a few hundred years ago, which, to a star, is a very short time. During that time, the star's position relative to Earth will not have changed significantly.

For a star to be millions of miles away as some claim they are. it would have to be in an entirely different galaxy. If you were to observe the Andromeda Galaxy through a telescope, you would see it as it was 2.5 million years ago. Since then, the stars in it will have moved, but most will still exist as most stars last for billions of years, not just millions.

How long does it take to get to Polaris if you are at the North Pole?

That will depend on where in the world you are starting from and what methods of transport you are using to get there. From most parts of the world, and with the proper transport, you could do it within two days.
