天の極

Translation

celestial axis point / celestial sphere pivot

Meaning

The point on the imaginary celestial sphere directly above the Earth's geographic poles, around which all stars appear to rotate due to the planet's axial rotation.

Examples

• The North celestial pole is currently aligned very close to the bright star Polaris.
  北の天の極は、現在、明るい星である北極星のすぐ近くに位置しています。
• Because the Earth wobbles on its axis over thousands of years, the celestial pole slowly shifts its position among the constellations.
  地球の地軸は何千年もの時間をかけて揺れ動くため、天の極は星座の間でゆっくりと位置を変えていきます。
