Uranus moon Miranda features the tallest cliff in the solar system

Verona Rupes is a sheer ice cliff dropping twenty kilometres deep

Uranus's small moon Miranda displays a chaotic jumble of fractured terrain, including giant fault scarps and canyon trenches. Verona Rupes is a sheer vertical ice cliff rising roughly 20 kilometres high, meaning a person stepping off the top would fall for over twelve minutes before reaching the bottom.
