is a large
Lunar Impact Crater that is located on the
Far Side of the
Moon . It is attached to the eastern rim of the equally-large
Keeler Walled-basin , although Keeler is somewhat less eroded than Heaviside. To the northwest lies
Stratton Crater , and to the southeast is the prominent
Aitken Crater .
The outer wall of the Heaviside formation has been worn and eroded by subsequent impacts, particularly to the north and south. Only the eastern rim remains relatively intact, while the western rim has been slightly distorted by the adjacent Keeler impact.
The relatively flat interior floor is marked by many small craterlets and rugged terrain to the southeast and west. The most notable of these are the satellite craters 'Heaviside N' in the south, 'Heaviside Z' in the north, and the bowl-shaped 'Heaviside E' near the eastern rim.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Heaviside crater.
