pohjantähden

Pohjantähden is a Finnish term that translates to "North Star" or "Pole Star" in English. It refers to the star that is currently closest to the north celestial pole, and therefore appears to remain almost stationary in the sky throughout the night. In modern times, Polaris, part of the Ursa Minor constellation, is the Pohjantähden. Its position close to the celestial north pole makes it a crucial navigational aid, particularly in the Northern Hemisphere. Sailors, travelers, and astronomers have historically relied on its consistent position to determine direction and latitude. The star's apparent stillness in the sky has also imbued it with symbolic meaning in various cultures, often representing constancy, guidance, and destiny. While Polaris is the current Pohjantähden, the Earth's axial precession means that the identity of the Pohjantähden changes slowly over millennia. In ancient times, Thuban was the Pole Star, and in the future, Vega will serve this role. The concept of the Pohjantähden, therefore, is not static but a celestial phenomenon that shifts over vast timescales.
