gravitational fieldRegion around a body in which other bodies experience a force due to its gravitational attraction. The gravitational field of a massive object such as the Earth is very strong and easily recognized as the force of gravity, whereas that of an object of much smaller mass is very weak and difficult to detect. Gravitational fields produce only attractive forces. |

| Scientists detected the ancient sear a decade ago after noting anomalies in the planet's magnetic and gravitational fields in that region, says Rodger J. The gravitational fields of these planets will pull on the spacecraft as it passes them, causing it to increase its speed, a phenomenon called gravity assist. When the gravitational fields of only two objects interact it is easy to calculate the results exactly. |
