Dhruva, also known as the Pole Star, is a prominent star located nearly directly above the Earth's North Pole. It is part of the Ursa Minor constellation and is often used for navigation due to its fixed position in the sky. Its brightness and stability make it easily recognizable, especially in the northern hemisphere. The name "Dhruva" comes from ancient Indian astronomy, where it symbolizes steadfastness and reliability. As the Earth rotates, Dhruva remains almost stationary, serving as a reference point for travelers and astronomers alike. Its significance extends beyond navigation, representing constancy in various cultures.
