Description

Additional Information

Quite large circle-shaped formation southwest of the Flamsteed P ring
What seems to be a circle-shaped formation southwest of the Flamsteed P ring is an arrangement of wrinkle ridges, more-or-less... well... circle shaped (see SLC-map F5). Is it perhaps part of the remains of the Flamsteed-Billy impact basin? - DannyCaes Feb 4, 2017

Nomenclature

Basins filled with maria are named for the mare, and basins that were previously recognized as craters still bear the crater name. Basins located between craters have the names of the two opposite craters with a hyphen in between, in this case Flamsteed and Billy.
