In the Ptolemaic system, Venus should not show phases.
 
  Indicate whether the statement is true or false

Question 2

The Kepler mission has searched for Earth-like planets by looking for the dip in the brightness of a star as a (potential) planet transits across it.
 
  Why will this technique actually miss the vast majority of planets around the stars it observes?

Answer to Question 1

FALSE

Answer to Question 2

By searching for transits, Kepler can only detect those planets with orbits cross our line of sight to the star. This means the orbit must be very close to edge-on. Because planetary systems around other stars will have random orientations to us, most planets will not cross our line of sight and cause a dip in the star's brightness.
