Also, a letter in "Sky & Telescope" magazine at this time pointed to apparently simultaneous impact craters on Earth (for example, the Clearwater Lakes in Quebec), suggesting that these craters were caused by pairs of gravitationally-bound objects. In 1993, the first asteroid moon was confirmed when the Galileo probe discovered the small Dactyl orbiting 243 Ida in the asteroid belt. The second was discovered around 45 Eugenia in 1998.

Face on Moon South Pole Face on Moon South Pole The Face on Moon South Pole is a region on the Moon (81.9° south latitude and 39.27° east longitude) that was detected automatically in an image from the Lunar Reconnaissance Orbiter by a computer system using face recognition technologies, as a result of a project that was part of the International Space App Challenge 2013 Tokyo. It is composed of craters and shadows on the moon's surface that, together, form an image resembling a face. The "Face on Mars" is a better known example. Human brains have the ability to detect ambiguous images displayed upon
