Feature on the moon

North Complex Apollo 15 panoramic camera image Coordinates 26°15′N 3°35′E / 26.25°N 3.59°E / 26.25; 3.59 Diameter 3.09 km[1] Eponym Astronaut-named feature

A telephoto view from the slope of [Mons Hadley Delta](/source/Mons_Hadley_Delta) at station 6A facing north shows [Dune crater](/source/Dune_(crater)) in the foreground, the [LM](/source/Apollo_Lunar_Module) *Falcon* near the center, and the crater *Pluton* within the North Complex beyond the LM.

**North Complex** is a feature on Earth's [Moon](/source/Moon), a group of hills in the [Hadley–Apennine](/source/Hadley%E2%80%93Apennine) region. It was an intended destination for the astronauts of the [Apollo 15](/source/Apollo_15) mission, but due to problems extracting a [rock core](/source/Core_sample) near the landing site, there was not enough time to make the journey. The hills are thought to be volcanic in origin, but this remains unconfirmed because no samples were collected there.

North Complex is located approximately 2 km east of Hadley Rille, and is about 3 km north of the Apollo 15 landing site itself.

The feature was named by the geologist [Gerald G. Schaber](https://en.wikipedia.org/w/index.php?title=Gerald_G._Schaber&action=edit&redlink=1),[2] and the name was formally adopted by the [IAU](/source/International_Astronomical_Union) in 1973.[1] The astronauts actually called the North Complex "Schaber Hill." The astronauts named many of the small craters on the North Complex, including the 800 m diameter crater informally named *Pluton*.[3]
