- Chemical Rocket Propulsion: A chemical rocket is attached to the asteroid and ignited.
- Solar Sail: A solar sail is attached to the NEO and effectively increases its cross-sectional area. This, in turn, increases the effect of solar pressure on the NEO.
- Solar Ablation: A series of mirrors and lenses focus sunlight onto the NEO, causing material on the NEO’s surface to be expelled.
- Laser Ablation: A spacecraft focuses a high-energy laser on the NEO, causing the material on the surface of the NEO to heat up and be expelled from the surface.
- Standoff Nuclear Detonation: A nuclear explosive device is detonated near the asteroid, causing the asteroid's outermost layers to vaporize.
- High Isp Rocket Propulsion: A high specific impulse (Isp) rocket is attached to the asteroid and fires its engines over an extended period of time (i.e. VASIMR)
- Mass Driver: A lander with drilling equipment attaches to the asteroid, drills material out, and ejects it at high velocity.
- Kinetic Impactor: A spacecraft traveling at high relative velocity is impacted into the asteroid.
- Gravitational Tractor: A spacecraft is stationed very near to the asteroid such that their mutual gravitational attraction pulls the asteroid off course.
