- Apollo 16's oblique south-looking orbital FAIRCHILD-metric (mapping) photograph AS16-M-0695 shows Ibn-Rushd slightly above and to the right of the frame's centre. The curious dome-like mass near the frame's right margin is Mons Penck.

  • Abu al-Walîd Ibn Rushd (Averroës) (1126 - December 10, 1198) was a Spanish-Arab philosopher, physician, and polymath: a master of philosophy, Islamic law, astronomy, geography, mathematics, medicine, physics, and science. He has been described as the founding father of secular thought in Western Europe. In astronomy, Averroes rejected the eccentric deferents introduced by Ptolemy. He rejected the Ptolemaic model and instead argued for a strictly concentric model of the universe. He wrote the following criticism on the Ptolemaic model of planetary motion: “To assert the existence of an eccentric sphere or an epicyclic sphere is contrary to nature. [...] The astronomy of our time offers no truth, but only agrees with the calculations and not with what exists.” Averroes also argued that the Moon is opaque and obscure, and has some parts which are thicker than others, with the thicker parts receiving more light from the Sun than the thinner parts of the Moon. He also gave one of the first descriptions on sunspots.
  • The crater Ibn-Rushd (Cyrillus B) was also known as Rossard. This was one of Felix Chemla Lamech's new names, but the I.A.U. did not accept that name.
