金星今日穿过太阳地球之间的连线,手机拍的,凑合看,一个是太阳投影,一个是望远
镜里面的。
看点:
1,直观地看看太阳多大,
金星与地球差不多大,
三点连线时候,金星距离地球的距离是太阳距离地球距离的大约三分之一,
也就是说这个金星的黑斑直径缩小三倍,再与太阳比,大致可以看出太阳相比与金星或
者地球是多大。
2,太阳上面的黑子清晰可见,有那么几个大的,当然还是比金星小很多
3,“It's all about time.The next Venus transit will be in 2117. That is 105
years from now. It's unlikely that anyone reading this today will still
exist then. Think about that: The next time the orbits of Earth and Venus
align just so to create a transit, the world will be entirely populated by
an entirely unborn generation. That essential point about time is really
what makes this transit worth a moment of your own.”

希望我们的小宝宝长命百岁活到那一天哈。
