| Name Proposed Chinese Near-Moon Constellation 1 | Historical/Estimated Launch | Location Elliptical Frozen Lunar Orbit An elliptical frozen lunar orbit (EFLO) is an orbit about the moon that typically is highly eccentric, with a much lower periapse altitude than apoapse. Because the Moon's gravity is very irregular, there is a limited range of stable orbits. "Frozen" orbits maintain desirable orbit geometry in the face of these gravity perturbations, and are thus popular for use. Many high-altitude Lunar orbits are in elliptical frozen orbits for this reason |
Detailed Location
55 deg inclination, 12h period, 300km periapse altitude, eccentricity of 0.668, arg. Periapse of 90 deg |
