2.在北半球观测星空，各星座是绕北极星做逆时针方向旋转吗

不是绕北极星做逆时针方向旋转，而是绕北天极做逆时针方向旋转。逆时针绕着北天极运动。注意是绕着北天极而不是北极星。北极星也要绕着北天极旋转，和地球自转方向有关。北天极与南天极的区别北天极是地轴和天球于北方相交的一点，即北半球星空旋转的虚拟中心点。如果我们延伸地球北方的轴线就会指向北天极。北天极位于小熊座内，北极星（Polaris）距离北天极角度差只有42′。

3.在南半球有什么值得一看的星座可供肉眼观测

天赤道以南的星座在南半球任何一个地方都可以看到.但我没留意过哪些是在哪个季节才能看到的.就把天赤道以南的星座给楼主说几个吧：

4.如何观测冬季星空有哪些著名星座，如何观测

英文的.,

5.为什么有的星座全年能观测到

大熊星座、小熊星座、仙后星座。北赤纬60°至北天极之间的较亮星座就只有大熊座,小熊座和仙后座,仙王座的亮度要比上述3个星座暗2.5～6倍多.而观测者用肉眼观测往往总是先看亮星所在的星座,所以天龙座,

6.怎样计算所在地可观测的星座

把自己所在地的纬度度数设为X，北半球的话X就是正数（比如，X就等于+40），即X=-30）用X-90，然后再用X+90，得出区间【X-90,X+90】。X+90如果超过90，即取最大值90；X-90如果小于-90，那么就取最小值-90。寻找赤纬度在这个区间内的星座即可。区间为【-50，其中右边的区间超过90了。

7.古埃及人通过观测星座在一年里的横贯天空情况，用什么计时

古埃及拥有相当水准的天文学知识，他们通过观测太阳和大犬座α星（即天狼星，的阴性名词形式）的运行制定历法”另外也有人认为金字塔是用来观测天狼星而建造的。通过对天狼星准确的观测。埃及人确定一年（天狼年，即一种恒星年）的长度为365.25天，与的计算长度相当接近。
