Does Uranus have a ring that is upside down?
the Planet itself is upside down.
The planets that have retrograde rotation are : Venus and Uranus. Venus and Uranus. Uranus only just qualifies as having retrograde rotation. Its axis is tilted at about 98 degrees, with its north pole (as usually defined) just below the planet's orbit plane. So Uranus is, just, "upside down" as it were.
