Bonpland is the remains of a lunar

Moon

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Impact crater

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Fra Mauro is the worn remnant of a walled lunar plain. It is part of the surrounding Fra Mauro formation, being located to the northeast of Mare Cognitum and southeast of Mare Insularum...

Parry (crater)

Parry is a lunar crater that is attached to the southeast rim of the walled plain Fra Mauro. Attached to the west and southwest rim of Parry is the crater Bonpland. Due south of Parry is the small crater Tolansky, and farther to the south-southwest is Guericke....

Tolansky (crater)

Tolansky is a small, circular lunar impact crater that is located due south of the crater Parry on the Mare Cognitum. The formation is symmetric, with a light-hued outer rim and a darker interior floor. A rille belonging to the Rimae Parry almost connects with the north-northwestern rim of Tolansky....

. Bonpland lies on the eastern edge of Mare Cognitum

Mare Cognitum

Mare Cognitum is a lunar mare located in a basin or large crater which sits in the second ring of the Procellarum basin. The basin material is of the Lower Imbrian epoch, while the basaltic mare material is of the Upper Imbrian epoch...

This rim of Bonpland is heavily worn and eroded, with the intrusion of Parry in the east creating a bulging extension to the southeast. The floor has been flooded by lava

Lava

Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...

 in the past, leaving a relatively flat surface that is broken by a series of narrow clefts. These are collectively designated the Rimae Parry. The clefts cross the rim to the south and also to the north, extending into the neighboring Fra Mauro.

Satellite craters

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 Bonpland.

  Kuiper (lunar crater)
  Kuiper is a small lunar impact crater in a relatively featureless part of the Mare Cognitum. It is a circular, cup-shaped feature with only some minor wear. This crater was previously identified as Bonpland E before being renamed by the IAU...
