Gerard Kuiper discovered the moon Miranda on the 16th of February 1948 using the Otto Struve Telescope at McDonald Observatory in Texas. He confirmed the moon's motion around Uranus by the 3rd of March 1948.
Miranda orbits roughly 129000 kilometers from the surface of Uranus with an orbital period lasting exactly 34 hours. This synchronous state means the moon always shows the same face toward Uranus while maintaining an unusual inclination of 4.34 degrees.
The Voyager 2 probe flew past Uranus on the 25th of January 1986 providing humanity's only close-up view of Miranda. Only the southern hemisphere faced the Sun when the flyby occurred leaving the northern side unobserved for decades until a 2024 study mapped that region using Voyager 2 images.
A density of 1.15 grams per cubic centimeter makes Miranda the least dense of all round Uranian satellites suggesting the body contains more than sixty percent water ice mixed with rock. Radioactive decay likely generated enough heat to separate silicate materials from organic compounds inside the core.
Verona Rupes stands as a sheer cliff reaching heights between five and ten kilometers making it potentially the tallest in the solar system. The fault system extends across the terminator where sunlight meets darkness near the edge of Inverness Corona.
