A) They formed as jovian planets close to the star in the same orbits that they are seen today.
B) They formed as dense, rocky planets close to the star in the same orbits that they are seen today.
C) They formed as jovian planets beyond the frost line and then migrated inward.
D) Many planets were formed around the star but coalesced into a single planet close in.
E) They spun off from the young star when it was rapidly rotating.
C) They formed as jovian planets beyond the frost line and then migrated inward.
