- 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.
Agayne ye haue hearde how it was sayd to the of olde tyme thou shalt not forsuere thy selfe but shalt performe thyne othe to God.
Matthew 5:33 TYN
