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 moon is not the only natural object traveling through space alongside Earth. Several small asteroids travel around the sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete ...

Earth has a group of cosmic stalkers. Known as "co-orbitals," these small bits of rock have a 1:1 mean motion resonance with Earth. Basically, they take the exact same amount of time to orbit the sun as we do. Astronomers ...
