The cameras of the Voyager II spacecraft detected six small, previously unseen moons circling Uranus, which doubles to twelve the number of satellites now known as orbiting the distant planet.
(A)        which doubles to twelve the number of satellites now known as orbiting
(B)        doubling to twelve the number of satellites now known to orbit
(C)        which doubles to twelve the number of satellites now known in orbit around
(D)        doubling to twelve the number of satellites now known as orbiting
(E)        which doubles to twelve the number of satellites now known that orbit

解释说B中to orbit 比D选项中的 as orbiting要好，哪位大牛能出来解释下吗？为什么选B而不是D？

be known as意思是：被认为是XXX；作为XXX被认知。
后面要加名词成分啊。
比如：
Tieling is known as a wonderful city.
而不是Tieling is known as wonderful.

B里面be known to do后面接动词没什么问题。
