A gravity tractor is a theoretical spacecraft that would deflect another object in space, typically a potentially hazardous asteroid that might impact Earth, without physically contacting it, using only its gravitational field to transmit the required impulse. The gravitational force of a nearby space vehicle, though small, is able to alter the path of a much larger asteroid if the vehicle spends enough time close to it; all that is required is that the vehicle thrust in a consistent direction relati… Webb30 juni 2015 · Techniques include the slow gravity tractor (spacecraft gravity pulls the asteroid), to the mid-range kinetic impactor (slam one or more spacecraft into the …
