Ancient Newton is the informal name for the ghost ring illustrated above, extending from the south rim of Plato, on the north, to Mons Pico, on the south.

Description: Elger

(IAU Directions)
PLATO.-- ... On the Mare Imbrium S. of Plato is a large area enclosed by low ridges, to which Schroter gave the name "Newton." It suggests the idea that it represents the ruin of a once imposing enclosure, of which the conspicuous mountain Pico formed a part.

MOUNTAIN RINGS.--These objects, usually encircled by a low and broken border, seldom more than a few hundred feet in height, are closely allied to the walled-plains. ... The curious formation on the Mare Imbrium immediately south of Plato (called "Newton" by Schroter), may be placed in this category ... these features have the appearance of having once been formations of a much more prominent and important character, which have suffered destruction, more or less complete, through being partially overwhelmed by the material of the "seas."

Additional Information

  • The location of Ancient Newton is also depicted on SLC-charts D1 and D2.


  • The ghost crater immediately south of Plato was called Newton by Johann Schröter (see his illustration).
  • That name was reassigned to a odd feature near the South Pole by Beer and Mädler, who referred to the present formation as Schröter's Newton. Schröter's ghost later became known as Ancient Newton (see, for example, Harold Hill, page 62). I don't know who first called it that. - tychocrater Jul 15, 2010
