The North Star is not an absolute guide to latitude on earth. Its position in the sky fluctuates with the earth’s axis. The planets and stars also rotate around the star. In the past, travelers relied on the star to determine their northern extent. Today, we can use Polaris to guide us. However, many travelers may be unsure of what this object is or where it is located in the sky.
Despite its name, Polaris is a variable star, a star which orbits the primary star at a distance of about 430 light years. It is also known as the North Star because of its position near the north celestial pole. It marks the way to travel due north. But, it is difficult to spot this variable star from the Earth. That’s why it is sometimes called the North Pole. The stars in the constellations that circle the North Pole are also referred to as the “Northstar”.
Astronomers consider Polaris a Cephid variable. The brightness of this star fluctuates about 10 percent every four days. In fact, ten years ago, this number dropped to 2%. Although this decrease was disappointing, it was predicted to slow down – and astronomers were not ready to give up on it just yet. A recent study of the stars in the northern sky revealed that the variability had increased to 4%.
If you are traveling in the Northern Hemisphere, you may have heard of the North Star. It’s a bright star in the sky that lies directly overhead. The polar region is 90 degrees latitude, so its position is 90 degrees north. When you’re at the Equator, you’ll see Polaris at 0deg. The star is located at RA 2h 41m 39”, Dec. +89deg 15′ 51”. It is the brightest star in the constellation Ursa Minor, so it is easy to locate by night.
In addition to its official name, Polaris has four nicknames. It is called the North Star because it appears directly overhead. It is also known as the ice-cream star. It has been observed that the pole star is 4.6 times brighter today than it was when Ptolemy first observed it. The polaris is the most prominent of the five polar stars and is visible only during daylight hours. The other three stars are the arctic triangle, the nebula, and the nebula.
It is located directly overhead at the North Pole, and is a bright star. If you’re looking for a star, you’ll find Polaris in the northern hemisphere. It’s in the constellation Ursa Minor. Its location is RA 2h 41m 39′, Dec. 89deg 15’51’. When you’re trying to find it, you’ll see it at the top of a mountain in the sky.
The North Star is a bright star that marks the north celestial pole. It is also located in line with the northern axis of rotation. If you’re at the North Pole, Polaris would be overhead in your sky. For the rest of your life, it will stay over the pole. You’ll find it in the evening skies. It’s a valuable tool for navigation and astrometry. When you’re out in the wild, you can point it with your hands.
The star Polaris is directly overhead at the North Pole. At this latitude, it’s 90 degrees above the Equator. Its brightness varies by about 0.03 magnitude over three days. It’s a bright star that’s often used in navigation. You can learn about it by using the QuizGriz website. The website is free and will deliver quizzes daily.

The constellation Polaris was first catalogued by Claudius Ptolemy in 169 AD, but it wasn’t used as a navigational tool until the 5th century. The star’s name is an acronym for Stella Polaris, which means “polar star”. It’s a bright star that’s always pointed to the north. This fact made it a very valuable navigation tool throughout history. It was the first North Star to be used for navigation.
