The North Star Among the multitude of stars in the universe, there are a couple that are of great importance to people. The sun, of course, is one of them. The other is known as Polaris, the North Star. Polaris is special because it is the only star that always appears to be in the same place in the sky. Therefore, Polaris is a great compass. When people in the northern hemisphere of Earth look toward Polaris, they can be certain that they are facing north. The permanence of Polaris in the north sky has helped countless people find their destinations. Before the invention of modern navigation tools, mariners relied on Polaris. Their technique was to look for Polaris to figure out their place at sea. They figured out the angle between the star and the horizon to determine their latitude. As long as the equations weren't erroneous, the results were very reliable. Polaris also let sailors determine North, South, East, and West. By knowing directions and their location, mariners could easily navigate their ships. To those who sail at night, wild storms and dark clouds were more than nuisances. They could disrupt entire journeys by blocking the view of Polaris. A captain could err and make an inadvertent turn, deviating from the correct course. The ship could become stranded at sea, and the frantic captain would have no way to improvise to get the ship back on the right course. The mariner's fears wouldn't be soothed until the clouds cleared and Polaris came back into view. Even today, sailors sometimes choose to navigate by using Polaris on clear nights. It's not difficult to differentiate Polaris from other stars. The Big Dipper, which is well known in astrology, appears to revolve around Polaris. The handle of the Big Dipper always points to the North Star. When people get lost, it's comforting to know that their problems can be solved by looking at the sky.

在宇宙中众多的星星中，有两颗对人类非常重要。 当然，太阳就是其中之一。 另一颗被称为北极星。 北极星很特别，因为它是唯一一颗总是出现在天空中同一个地方的星星。 因此，北极星是一个伟大的指南针。 当地球北半球的人们望向北极星时，他们可以肯定自己正面向北方。 北极星在北方天空的永恒帮助无数人找到了他们的目的地。 在现代导航工具发明之前，水手们依靠北极星。 他们的技术是寻找北极星来确定它们在海上的位置。 他们计算出恒星和地平线之间的角度来确定纬度。 只要方程式没有错，结果就非常可靠。 北极星还能让水手们确定北、南、东、西。 通过知道方向和位置，水手们可以很容易地导航他们的船只。 对于那些在夜间航行的人来说，狂风暴雨和乌云不仅仅是令人讨厌的东西。 它们可能会挡住北极星的视线，从而扰乱整个旅程。 船长可能会犯错误，在无意中转向，偏离正确的航线。 船可能会搁浅在海上，而疯狂的船长将没有办法让船回到正确的航线上。 直到云层散去，北极星重新出现在人们的视野中，水手的恐惧才得以缓解。 即使在今天，水手们有时也会选择在晴朗的夜晚使用北极星导航。 将北极星与其他恒星区分开来并不难。 北斗七星在占星术中是众所周知的，它似乎围绕着北极星旋转。 北斗七星的柄总是指向北极星。 当人们迷路的时候，知道他们的问题可以通过仰望天空来解决，这是令人欣慰的。
