Description

Fresh crater with impact melt dark collar and asymmetric rays indicating oblique impact. Melt in floor. Ohm's rays extend 1800 km to Aristarchus Plateau.

Additional Information

  • Possible oblique impact – a dark collar (impact melt like Tycho) most evident to NNE, width 0.7 crater diameter. [Kirata et al LPSC 30: 1350]

  • USGS Geology map I-1034 depicts this as an Eratosthenian age crater, but the bright and extensive ray pattern - perhaps not visible on the images they had 30 yrears ago - confirms this as being of Copernican age. - tychocrater tychocrater Oct 21, 2007

Nomenclature

Georg Simon Ohm (March 16, 1789 - July 6, 1854) was a German physicist. As a high school teacher, Ohm started his research with the recently invented electrochemical cell, invented by Italian Count Alessandro Volta. Using equipment of his own creation, Ohm determined that the current that flows through a wire is proportional to its cross sectional area and inversely proportional to its length or Ohm's law. Using the results of his experiments, Georg Simon Ohm was able to define the fundamental relationship among voltage, current, and resistance which represents the true beginning of electrical circuit analysis.
