On the landing, a combination of thrust from residual pressure in the docking tunnel that connected the Lunar Module with the command module Columbia in orbit, and an imperfect understanding of the Moon's uneven gravitational field, resulted in navigation errors which pushed the powered descent initiation point about 3 miles (4.8 km), and thus ...
Apollo lunar missions would begin with a nominal 100-nautical-mile (185.2 km) circular Earth parking orbit. Apollo 8 was launched into an initial orbit with an apogee of 99.99 nautical miles (185.18 km) and a perigee of 99.57 nautical miles (184.40 km), with an inclination of 32.51° to the Equator, and an orbital period of 88.19
