In What Way Are Many of the Extrasolar Planetary Systems

question 1

Multiple Choice

In what way are many of the extrasolar planetary systems that have been discovered so far fundamentally different from our own solar system?

• A) The relative positions of where the planets formed are inverted, with the Jovian-type planets forming close to the stars and the terrestrial-type planets forming farther out.
• B) Many terrestrial planets discovered so far have masses intermediate between the terrestrial planets of our system and the ice giants.
• C) The massive Jovian-type planets appear to have formed at large distances, like our own Jovian planets, and then spiraled in close to their stars.
• D) There are no Jovian-mass planets.
