Can we stop an asteroid from hitting Earth?
Kinetic impactor Kinetic impactors are one way by which we might be able to alter an asteroid's path. In principle, this technique requires smacking an asteroid to change its orbit around the sun so it no longer is a threat to Earth.
Can asteroids move the Earth?
No. The Earth has a lot of mass and moves extremely quickly in its orbit around the Sun; in science speak, we say its 'momentum' is large. To significantly change the Earth's orbit, you would have to impart a very great change to the Earth's momentum.
Could we be able to divert asteroids?
NASA confirms that its DART spacecraft 'nudged' the asteroid Dimorphos into a new orbit. Humans have for the first time proved that they can change the path of a massive rock hurtling through space.
