A star is a luminous celestial body composed of plasma, generating light and heat through nuclear fusion. The Pole Star, also known as Polaris, is a prominent star located nearly directly above Earth’s North Pole. It is used for navigation due to its stable position in the sky relative to Earth’s rotation axis.

A star is a massive, luminous sphere of plasma held together by gravity, undergoing nuclear fusion in its core, which produces light and heat. Stars are fundamental components of galaxies and are central to the study of astrophysics. The Pole Star, or Polaris, is a specific star located close to Earth’s North Celestial Pole. Its nearly fixed position in the sky relative to the rotation axis of Earth makes it a crucial reference point for navigation, particularly in the Northern Hemisphere. Polaris is part of the constellation Ursa Minor and has been used historically by sailors and explorers to determine direction and latitude.
