Miranda
Miranda is the smallest and innermost of Uranus's five round satellites. Like the other large moons of Uranus, Miranda orbits close to its planet's equatorial plane. Because Uranus orbits the Sun on its side, Miranda's orbit is perpendicular to the ecliptic and shares Uranus's extreme seasonal cycle. At just 470 km in diameter, Miranda is one of the smallest objects in the Solar System known to be spherical under its own gravity. Of the bodies that are known to be in hydrostatic equilibrium, only Saturn's moon Mimas is smaller. Miranda has one of the most extreme and varied topographies of any object in the Solar System, including Verona Rupes, a 5- to 10-kilometer-high scarp that is the tallest cliff in the Solar System, and chevron-shaped tectonic features called coronae.
