| − | Is Achille’s image the first knowingly taken of the 5 km wide crater [http://the-moon.wikispaces.com/Petit Petit]? I know that I have observed this region and must have seen the bright crater, but did not guess that it had a name. Is it called Petit because of its size? Or because 151 years ago Frederic Petit announced the discovery of a very small [http://www.math.ucdavis.edu/~cheung/lilith.html second Moon] that circled Earth every 2 hours 44 minutes and 59 seconds? No, the name was approved in 1976 not for these lunar reasons, but only because it appeared on a large scale topographic [http://www.lpi.usra.edu/resources/mapcatalog/LTO/lto62c4_1/ map] published by NASA in 1974. Despite this inauspicious naming, the little crater does serve one of the main goals of a named piece of geography - it is a landmark. It is almost blindingly bright at [http://www.lpod.org/coppermine/displayimage.php?album=28&pos=80 full Moon] and as the Apollo 17 image reveals, it is a dramtic oblique impact feature. I bet that everyone will knowingly observe it now.</p> | + | Is Achille’s image the first knowingly taken of the 5 km wide crater [https://the-moon.us/wiki/Petit Petit]?
