标题[问题] 南半球的陨石比北半球少？
时间Thu Apr 10 21:51:03 2008
这是我的英文课本的其中一段话
Today,the governments of serveral countries try to locate
NEAs(near-Earth asteroids). Universit and amateur astronomers
also watch out for dangerous asteroids. However,there are problems.
First,most asteroids are small and dark. That makes then difficult
to spot. Second,if an asteroids is coming from the direction of
the sun,it cannot be seen because the sun is too bright.
Finally,thereis no large-scale program in the southern hemispthere
to try to find asteroids.
中间说的又黑又小所以不好找这还理解
不过後来说的”从太阳来的asteroids命中南半球的机率比北半球小”
这就不太清楚了
是因为南半球的面积比较少这样而以吗？
还是还包含地球倾斜的角度、形状(椭圆形)...等
或者还有其他理由呢？
请内行解答，谢谢！

4F：→ assddd0206:我是想说，南半球的NEAs没有高机率被找到，加上前面从 04/10 23:26
5F：→ assddd0206:太阳来的，所以我才这样解读，主要就是想问说为什麽南 04/10 23:27
6F：→ assddd0206:半球的机率会不高？ 04/10 23:28
