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
