the problem with this sentence is that the underlined portion is fragment and does not have verb.. on the other hand it needs to follow a parallel structure with "and orbits" ==> to fix these problems we need to have "the planet, known as..., HAS a mass of....."
(A) The planet, known as CoRoT-2b, having a mass about three times that of Jupiter's -- 1,000 times that of Earth's -- and orbits its parent star, CoRoT-2a at a distance roughly 10 times the distance between Earth and the moon. out

(B) The planet, known as CoRoT-2b, has a mass about three times that of Jupiter -- 1,000 times that of Earth -- and orbits its parent star, CoRoT-2a at a distance roughly 10 times the distance between Earth and the moon. correct

(C) The planet, known as CoRoT-2b, having a mass about three times more that of Jupiter -- 1,000 times more that of Earth -- and orbits its parent star, CoRoT-2a at a distance roughly 10 times the distance between Earth and the moon. out

(D) The planet, known as CoRoT-2b, has a mass about three times that of Jupiter's -- 1,000 times that of Earth's -- and orbits its parent star, CoRoT-2a at a distance roughly 10 times the distance between Earth and the moon. "of-phrase" and "possessive 's" can not be together (that of jupiter's)

(E) The planet, known as CoRoT-2b, having a mass about three times greater that of Jupiter's -- 1,000 times greater that of Earth's -- and orbits its parent star, CoRoT-2a at a distance roughly 10 times the distance between Earth and the moon. out
