in solar system
● Takes 88 days to revolve around the Sun
● Mathematics:
- 4 x the revolving time of Mercury= Year on
Earth
● It takes 59 days to complete one rotation on its
axis
● No natural satellite/an orbiting object!

The big, star-shaped crater towards the
bottom of the globe is named Debussy.
