- One day there (time for it to spin once) takes as long a 243 Earth days.
- Has no moons

- One year is 29 Earth days
- Not a terrestrial planet
- Has 62 moons- some COULD support life
- Has 7 rings with gaps and divisions between
8. Uranus
- One day is 17 Earth hours
- One year is 84 Earth days
- Not a terrestrial planet
- Has 27 moons and also has faint rings
- Also is retrograde rotation
9. Neptune
- One day is 16 Earth hours
- One year is 165 Earth YEARS
- Not a terrestrial planet
- Has 13 moons and 6 rings
Hope this helped!
