a. 62
b. 63
c. 65
d. 67

ANSWER: 67
 
Astronomers have found there are more planets of the hot Jupiter type than previously expected in a cluster of stars called Messier 67, to understand planet formation.
  • The open cluster star is the same age as the Sun and it is believed the Solar System operated in a similarly dense environment
  • Hot Jupiter is a giant exoplanet with mass of close to more than a third of Jupiter’s mass
  • These are hot as they are orbiting close to parent stars indicated by orbital period less than 10 days in duration
