description is accurate. Uranus has a 17 hour and 14 minute day and takes 84 years to make its way about the sun with an axis tilted at around 90¢X with retrograde rotation. Stranger still is the fact that Uranus ’ axis is almost parallel to the ecliptic‚ hence the expression "on its belly.¡¨ Uranus is so far away that scientists knew comparatively little about it before NASA ’s Voyager 2 undertook its historic first encounter with the planet. The spacecraft flew closely past distant Uranus‚
