[ noun ] (astronomy) the sun with the celestial bodies that revolve around it in its gravitational field
Used in print (Frank Oppenheimer, "Science and Fear-- A Discussion...)This and other fears of the solar_system have disappeared gradually , first , with the Ptolemaic_system and its built-in concept of periodicity and_then , more firmly , with the Newtonian innovation of an universal force that could account quantitatively for both terrestrial and celestial motions . Our understanding of the solar_system has taught us to replace our former elaborate rituals with the appropriate action which , in this case , amounts to doing nothing . (J. F. Vedder, "Micrometeorites", in Francis S. J...)The radius is calculated from the mass by assuming spheres of density * * f except for the smallest particles , which must have a higher mass density to remain in the solar_system in the presence of solar_radiation pressure . (James Thurber, "The Future, If Any, of Comedy,"...)`` The human ego being what it is '' , I put_in , `` science_fiction has always assumed that the creatures on the planets of a_thousand larger solar_systems than ours must look_like gigantic tube-nosed_fruit_bats . |
