B
The gravity of the star that extrasolar planets orbit causes the extrasolar planets to visibly "wobble."
C
The mutual gravity of an extrasolar planet and the star that it orbits causes an irregular orbit.
D
The gravity of extrasolar planets is stronger than the gravity of planets that orbit our Sun, causing faster orbits.
