Key science: Stellar dynamics, N-body simulations, planetary orbital stability, and galactic gravitational potentials.

Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of ...

A computer visualization maps small bodies in the solar system that are expected to be observed by the Rubin Observatory during the 10-year Legacy Survey of Space and Time. Red indicates near-Earth ...

Parallel N-body simulations form the computational backbone for modelling the dynamical evolution of astrophysical systems, from planetary rings and protoplanetary discs to galaxy clusters and ...

Astronomers could multiply the known catalog of planets outside our solar system by a factor of roughly 16 in a single ...

Gas-giant planets have been detected on eccentric orbits several hundreds of astronomical units in size around other stars. It has been proposed that even the Sun hosts a wide-orbit planet of 5–10 ...

Scientists have discovered a bizarre planetary system where a rocky world orbits farther out than giant gas planets, defying long-standing theories of planet formation. The finding hints that some ...
