Heaviside 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.
