Oersted is 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...

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...

, leaving only a crescent-shaped rim with a gap to the southwest. The rim climbs to a maximum height of 1.7 km. This feature lies to the southeast of the crater Atlas

Atlas (crater)

Atlas is a prominent lunar impact crater that is located in the northeast part of the Moon, to the southeast of Mare Frigoris. Just to the west is the slightly smaller but still prominent crater Hercules. Northeast of Atlas is the large Endymion....

, and southwest of Chevallier

Chevallier (crater)

Chevallier is a lunar crater that is located in the northeastern part of the Moon's near side, about a crater diameter east-southeast of the prominent crater Atlas. To the south-southeast of Chevallier is the flooded crater Shuckburgh....

. To the south-southwest is Cepheus

Cepheus (crater)

Cepheus is a lunar impact crater that is located in the northeastern part of the Moon, within one crater diameter of the larger crater Franklin to the southeast. To the north-north-east is the flooded crater Oersted...

.

The northern rim of Oersted is overlain by a broken, lava-flooded craterlet. Just to the south is a younger, still-intact crater named Oersted A that was formed after Oersted was flooded. To the northwest, the flooded crater Oersted P is attached to the northwest arm of the outer rim.

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 Oersted.
