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 ...

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 ...

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 ...

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 ...
