Planets by the length of one full rotation (hours)

About this puzzle
A planet's day has nothing to do with its year, its size, or its distance from the Sun - it is simply how long one turn on its axis takes. The values span from under half an Earth day to well over two hundred, and the ordering rarely matches anyone's intuition about which worlds are fast and which are slow. All figures are given in Earth hours.
