The planet COROT- 14b is only slightly larger than Jupiter, but is several times more massive. Which is the most plausible explanation for its similar size to Jupiter?
A)The hydrogen and helium gas compressed even under their own gravity to a higher density than Jupiter.
B)It is made of elements other than hydrogen and helium which do not compress under their own gravity.
C)Planets that are close to a star are heated up and therefore larger.
D)The mass measurement is mistaken, and it is actually about 10 times more massive than Jupiter.
