NASA, along with a suite of international and private partners, has plans to build a small space station Called Lunar Gateway.
The current plan is to place Gateway in a near-rectilinear halo orbit, or NRHO.
This fuel-efficient orbit takes advantage of neutral gravity points generated by the Earth and the Moon.
NRHO is highly elliptical, so the space station will come to within approximately 1,865 miles (3,000 kilometers) of the Moon during its closest approach but then travel out to a distance of 43,500 miles (70,000 km).
The European Space Agency (ESA) says Gateway will support four astronauts for 90-day stays.
