Current evidence suggests that many massive jovian planets orbit at very close orbital distances to their stars. How do we think these planets ended up on these close orbits?
A. These planets are jovian in nature and were able to form close to their stars because their solar nebulas were very cold in temperature.
B. These planets migrated inward after being born on orbits much farther from their stars.
C. Despite their large masses, these planets are terrestrial in nature and therefore could form in their inner solar systems.
D. These planets were captured from other solar systems.
