more than twice that exerted

There seems to be something wrong with this sentence., or some different structure I have not heard of so far. Can you please help me understand the sentence?

"The sun's gravitational pull on the moon is more than twice that exerted by the Earth"

I can understand the highlighted part here but not the one above. e.g : "The Sun's gravitational pull on the moon is twice more than that exerted by the Earth" Apparantly this is a ruduction of (...that which is exerted). Yet with or without a reduction, the first sentence sounds incomprehensibly odd to me.

I can understand this highlighted part too : "The Sun's gravitational pull on the moon is more than twice that is exerted by the Earth"

What's missing in the first sentence- if any? What kind of a sentence is this yaw? I need a parsing and a paraphrase.

I think Kili finds the place of TWICE weird. Can TWICE be used as an adjective in front of a noun or a pronoun?

You have "exerted by" intead of "of."

The pull is twice that of the earth. The pull is twice that exerted by the earth. Those are the same.
