<ul><li>時角系統像地理坐標系統一樣，被固定在地球的表面上。</li> <li>赤經系統被固定於恆星上（實際上並非如此，請參考<a href="/wiki/%E6%AD%B2%E5%B7%AE" title="歲差">歲差</a>和<a href="/wiki/%E7%AB%A0%E5%8B%95" title="章動">章動</a>）。</li></ul> <p>因此，在經過一夜或數個夜晚，就能看出來星星在天空中的位置移動了，當然，這並非恆星在天球上的運動，只是地球運動造成的。因為歲差和章動的影響，在相當長的時間間隔下所做的觀測，就必須註明所使用的特殊<a href="/wiki/%E6%9B%86%E5%85%83" title="曆元">曆元</a>，為行星、恆星、星系等等的位置做記錄。現在使用的曆元是<a href="/wiki/J2000.0" title="J2000.0">J2000.0</a>分點，稍早期使用的是<a href="/wiki/B1950.0" title="B1950.0">B1950.0</a>分點。 </p><p>赤道坐標系統中與緯度相似的值是赤緯（縮寫為 DEC），是天體在天球赤道上方或下方的角度。與經度對應的是赤經（縮寫為 RA），是與<a href="/wiki/%E6%98%A5%E5%88%86%E7%82%B9" class="mw-redirect" title="春分点">春分點</a>的角度距離，不同於經度的是赤經以時、分、秒為單位，而非度、分、秒。因為地球的運動造成赤道坐標系統的視運動，就會造成<a href="/wiki/%E6%81%92%E6%98%9F%E6%97%B6" title="恒星时">恆星時</a>和<a href="/wiki/%E6%99%82%E8%A7%92" title="時角">時角</a>的相對變化。將天球運轉一週的時間定為24小時，所以每小時天球會轉動15度（360° / 24h = 15）。 </p><p>赤道坐標系統也是<a href="/wiki/%E8%B5%A4%E9%81%93%E4%BB%AA" title="赤道仪">赤道仪</a>上很普通的設備，也就是<a href="/wiki/%E5%AE%9A%E4%BD%8D%E5%9C%88" title="定位圈">定位圈</a>。定位圈與<a href="/wiki/%E6%98%9F%E5%9C%96" title="星圖">星圖</a>或<a href="/wiki/%E6%98%9F%E6%9B%86%E8%A1%A8"
