The Earth–Moon system as a research area encompasses the coupled dynamical, geophysical, geochemical, and space-environment interactions between Earth and its natural satellite, studied using observational, theoretical, and numerical methods. It includes investigations of orbital and rotational dynamics, tidal dissipation, angular momentum exchange, and long-term evolution of the Earth–Moon distance and obliquity. Research targets internal structure and thermal histories inferred from gravity, seismology, and magnetic data; surface and exospheric processes; impact cratering; and volatile and isotopic compositions. The field also examines Earth–Moon space weather, plasma and magnetospheric interactions, and implications for planetary system formation, comparative planetology, and future exploration architectures.

The Artemis astronauts entered the final phase of their run-up to a lunar loop on Monday, a tipping point of sorts that means the moon's gravity is now having a stronger pull on the spacecraft than Earth's.
