Stargazing is fun and appealing. But, not being able to see clearly with a telescope can be frustrating. We have all been there.
But, don’t lose hope because we have a detailed article for your better understanding.
So, what color is Polaris?
The Polaris goes from yellow to white. Because it sometimes shines bright and sometimes, it dims out. Besides, Polaris is a triple star system. The primary star is the supergiant star because of its mass. That is six times of sun. The primary star is Polaris A and other two are Polaris Ab and b.
Now you know the color of Polaris. But to understand elaborately, keep reading!
What is Polaris?
First, you have to understand what Polaris is. Well, Polaris is known as a north star. Because it stays still close to the northern celestial pole. At this point, the entire northern sky moves. Polaris indicates the north.
But, that does not mean it stays in the north from every planet. It is in the north only for earth and in a 2d space. The direction varies from planet to planet. Also, it is a star of Ursa minor.
However, unlike other bright stars, Polaris is less bright at night. But you can see it with naked eyes. Because it is only the 48th brightest star. Also, even on a full moon, Polaris can be seen shining in the northern sky.
As it can be seen with naked eyes, it is used for navigation. Especially, sailors use it for finding their way and keeping track. If anyone loses the direction, he can always look at the Polaris. And know the direction of true north.
Now you know what Polaris is. So, let’s not wait and get to our next segment.
How to See It?
Well, as said earlier, Polaris can be seen with naked eyes. But you cannot see very clearly through eyes only. First of all, you need a higher quality and aperture telescope. A 70mm telescope can make you see Polaris perfectly.
Now, what you need to do is, take the help of a star pattern. It is a group of stars named the big dipper. In addition, it is the most famous star pattern in the northern hemisphere.
For finding Polaris, you have to search for the pointer stars of the big dipper. The pointer stars are Dubhe and Merak respectively. The exterior section of the Big Dipper’s bowl is outlined by these two stars. Also, these point to Polaris.
This is why draw a straight line from Merak through Dubhe. Now, multiply the distance from Merak to Dubhe 5 times. And finally, complete the multiplied distance. You will find Polaris at the end of it.
Well, you have found Polaris. What next? Finding out the color of Polaris that we will elaborate in the next segment.
What is the Color of Polaris?
After finding Polaris, you can see that it is a triple star system. This means the single spot you have been seeing shining all along is three stars. They are orbiting a common center. The three stars are,
It is called the primary star. Also, it is named a supergiant. Because it is six times the mass of the sun. And, the radius is 37.5 times that of the sun. Besides, the surface temperature is 6000 k.
It is the second star and, orbits close to the primary star which is 2 billion miles. This has a mass of 1.26 solar masses and a radius of 1.04 solar. Also, it emits three times the amount of light as the Sun.
It is the third star that orbits. Polaris B is roughly 240 billion kilometers away from Polaris A. This has a mass of 1.39 solar masses and a radius of 1.38 solar radii.
Furthermore, Polaris Ab and B have the same temperature as Polaris A. Even though both are dwarf stars.
It is said that Polaris is 430 light-years away. Which makes it a luminous star as the distance is huge. But sometimes it goes from bright to dim and vice versa.
This is why the distance is not fully accurate. It is an assumption.
So, Polaris is a yellow-white supergiant star that has a luminosity of 2500 suns. Because it goes from yellow to white for the distance.
Here the yellowish part is the primary star Polaris A. In addition, the whitish part is the two dwarf stars Polaris Ab and B.
So you know the color of Polaris. But this article cannot end without suggesting to you the best telescope to see Polaris. These will work out great for you.

These are the best telescopes that you can use to see Polaris a bit clear. These telescopes can reach distant objects easily. Also, experience stargazing on another level!
Question: What is a falling star?
Answer: It is a meteor. Here, portions of the meteoroid hit the earth after surviving the burning process. And, it is referred to as a meteorite. You might expect to see a lot of meteors in the night sky at certain periods of the year.
Question: What is the color of a shooting star?
Answer: The colors are firstly red, then white and finally blue. A shooting star seems like a quick flash of white light to the bare eyes. However, it shows a wide range of colors on their way towards earth. The order of these colors is predictable.
Question: Why do stars twinkle?
Answer: Light from stars bounces its way through various layers while traveling through the atmosphere. The bouncing bends the light before anyone can see it. Because of the constant movement of hot and cold layers of air, the bending varies. And, it causes the stars to twinkle.
To conclude, we have successfully reached the end of the article – what color is polaris. Now you know, the color of Polaris goes from yellow to white now and then.
We hope the discussion has been helpful to you. Thus you can understand the world of stargazing.
Till we meet again, Goodbye my friend!
