Exoplanetary systems containing hot Jupitersextremely massive planets orbiting very close to their parent starsdo not look like our own solar system. Are they inconsistent with the condensation theory of solar system formation? Explain.
 
  What will be an ideal response?

Question 2

In 1974, a radio message was sent out from the Arecibo observatory in Puerto Rico towards a globular cluster, 21,000 light-years away. Approximately how far has this message gotten as of today?
 
  A) It's just passing stars that are close neighbors to the Sun in the Milky Way.
  B) It's just beyond the Neptune in our solar system
  C) It's just passing through the Oort cloud surrounding our solar system
  D) It's already arrived at the globular cluster.
  E) It's almost at the center of the Milky Way.

Answer to Question 1

The existence of hot Jupiters is not at all inconsistent with the condensation theory; the process can easily deposit large planets in orbit very close to the parent star, without necessarily precluding the formation of Earthlike planets further away. Friction between the planets and the nebula may have caused the hot Jupiters' orbits to decay quickly.
