escape velocity

subject fact

escape velocity has definition Speed a satellite must attain in order to free itself from returning to the parent body under the effects of gravity. has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:33:27.0
has definition The speed at which an object can leave another object behind, without being recalled by its gravitational force. The escape velocity of Earth - which must, for instance, be attained by a spacecraft if it is to reach another planet - is 25,000 miles per hour. has source: Ferris, T. 1988 Coming of Age in the Milky Way, Morrow, 2001-09-27 09:33:27.0
has definition The velocity that a body requires to achieve a parabolic orbit around its primary (V_e = sqrt(2GM/R)). Escape velocity at Earth's surface is 11.2 km s^-1; of Moon, 2.4 km s^-1; of Sun, 617.7 km s^-1 (cf. orbital velocity). has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:33:27.0
