- The Earth and the Moon form the Earth-Moon satellite system with a shared center of mass, or barycenter. This barycenter stays located at all times 1,700 km (1,100 mi) (about a quarter of Earth’s radius) beneath the Earth’s surface, making the Moon seemingly orbit the Earth.
Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
Matthew 7:14 KJV
