How to find the North Star: constellation features

Residents of the Northern Hemisphere are not wondering how to find a polar star. From an early age, it is no problem to determine where the north side is and find Cepheid – another name of the northern star. The night sky helps travelers, lost travelers find the right path. The fact is that the heavenly body is always in the same place and more precisely the compass orients it according to the terrain, and this is often used by astronomers. After all, the height of Cepheids above the horizon coincides with the geographical latitude. Many simply admire the starry sky and know – this is the bright point of the polar star. But still, how to navigate and find, we will reveal the basic techniques.

Constellation features

How to find the polar starTwo bright constellations – the small and big bear occupy opposite sides and mirror each other. The big dipper forms a large bucket of 7 bright stars, which can be immediately seen in the night sky, helping to determine the location of the opposite constellation. Ursa Minor is located on the 56th largest place, consists of 29 celestial bodies. Constellation form a small bucket in the form of a trapezoid with a long handle, at the end of which is Cepheid.

This light belongs to the class of supergiants 23 times the Sun, 4 times heavier. Astronomers determined that the brightness of the celestial body is increasing and for today’s people it shines brighter than 2500 times. It is known that hot sun, yellowish color. Scientists have not determined the exact data on the distance from the earth, they roughly equate to 434 light years. Still, how to find a polar star?

Step-by-step instruction

It is easy to orient yourself in the sky, the monitoring system for the constellation of the Little Dipper and Cepheid takes many years, gained some experience from the times of our ancestors. Let’s proceed step by step instructions:

  1. It was said above that the Little Bear is a mirror image of another constellation. Find a big bear.
  2. In this constellation, we will find a large bucket, where there are two extreme stars forming a scoop.
  3. Begin to mentally draw a line from the upper, pale luminaries (Merak) to a brighter celestial body (Dubha).
  4. Continue the line and find the Polar Star.

Be sure to find a large bucket with 7 bright lights and only then look for the North Star.
Remember, at dusk and at dawn, one can be seen, the so-called Evening or Morning Star – this is the planet Venus. If you look in the direction of the South, you can see the brightest and lonely star Sirius. These celestial bodies, many refer to the North Star, but it is not. Consider other ways.

Modern methods

how to find the polar starUse technical tools to find Cepheid in the sky. You can take a picture of the night sphere. It is known that the celestial bodies are moving, and the polar star, located almost in the middle of the sphere, almost does not move. The photo shows moving celestial bodies that have made their way like glowing tracks forming circles from the shortest. Long tracks are fast stars, and polar ones are very slow, so the track is short and can be distinguished immediately. To get such a snapshot, you need to set the focus to infinity, the ISO 400–600 hypersensitivity, this mode can be kept for 30 minutes. Fix the camera and wipe off moisture.

You can install in your phone a special application for iOS – SkyGuid, Android – Stellarium, there are many other analogues. Such an application determines the constellation with the camera or calculates the position from a given place, time of day and season. And if, at hand, there is no technology, then what?

Ancient methods

If you do not know in which direction the north, the search is difficult. Determining the northern direction will easily orient to the desired constellation. Take two sticks, one slightly higher than the other. Place them on the ground, vertically high slightly ahead of a short stick. Lie in front of sticks, align your eyes, forming a straight line between your eyes and two sticks. Wait for some star to appear in front of the line of sight, look for a few minutes and wait for further movement. Oriented by the movements of the heavenly body. Up – east, down – west, to the right – south, to the left – north. Peer into the north side of the sky, Cepheid is in this area.

Being in a place where moss grows, you can easily find the north. Note if the moss on which side grows vertically on the tree. Since moss requires a humid atmosphere for growth, they choose the north side for this.

Follow the recommendations and find the polar star.
