2 which和as引导的非限制性定语从句的位置问题

网课上说which引导的非限制性定语从句只能放在主句之后。例如:

He is a famous scientist,which is well known.

但这一句:

The moon which is 384400 kilometers away from the earth,creates many beautiful stories.

1. 为什么这里which引导的非限制性定语从句可以放在主句之中?

2. as引导的非限制性定语从句可放在主句之前,之中和之后,那如果是放在主句之中,具体是放在哪个位置呢?

which引导的非限制性定语从句可以放在主句的后面,也可以插在主句中间,但是不能放在主句的前面如:

He gave me the book, which proved to be very interesting. 他给我的那本书真是有趣。(摘自《英汉多功能词典》新编升级版p.1940

Budapest, which is on the Danube, is a beautiful city.  位于多瑙河畔的布达佩斯是个美丽的城市。(同上

   关系代词 as 引导非限制性定语从句时,定语从句可放在主句之前,之中和之后。例如:

He was an American, as I knew from his accent. 他是个美国人,这是我从他的口音知道的。 (整个前句作为先行词)(摘自《英汉多功能词典》新编升级版p.93

As is often the case with him, he broke his promise. 一如往常,他又食言了。 (整个后句作为先行词) (同上) 

As was expected, he easily won (the) first prize. 他轻而易举地获得头奖,这是早已料到的事。 (整个后句作为先行词) (同上)

David, as you know, has not been well lately. 你知道的,戴维近来身体不太好。(摘自《朗文高级英语应试词典》英汉双解p.108( David has not been well lately 是主句)
