First, the danger must be detected way ahead of time. Second, something would have to be done to change their orbits. For example, making atom bombs explode on or near their surface has been considered. If detected way in advance, a small change in its direction could take it away from Earth. This is all hypothetical - so far, no Near Earth Object has been thus stopped.
Yes because large asteroids heading for earth are Near Earth Objects and if they were to hit many people can lose their lives.
NASA's Near Earth Objects program is one group that tracks object that pass near the Earth (you might have expected that from the name).
Gravity acts on all objects with mass. In the context of the Earth, gravity mostly acts on the Earth itself and objects on or near its surface.
An extraterrestrial object hitting Earth can cause significant damage depending on its size and speed. It may result in a crater, shockwaves, fires, and tsunamis, potentially leading to widespread destruction and loss of life. Scientists closely monitor near-Earth objects to assess potential impact risks and develop strategies to mitigate them.
Gravity is the force that pulls everything towards the center of the Earth. This force is created by the mass of the Earth and all objects on or near its surface.

Near-Earth Objects. Comets, meteors, and other things in space that are near Earth.

Not in the near future. It is inevitable that earth will be hit eventually, but a significant impact might not occur for thousands, even millions of years. Currently, NASA does not know of any objects that have a significant risk of impacting earth.
Astronomers use telescopes to regularly monitor and track near-Earth objects (NEOs) to identify potential threats. They also share information with organizations like NASA's Center for Near-Earth Object Studies (CNEOS) to determine if any NEOs pose a risk of impact. Additionally, researchers are working on technologies to deflect or destroy potentially hazardous NEOs if necessary.

Objects that fall near Earth's surface are rarely in free fall because air resistance exerts a force on the falling objects. This force opposes the force of gravity, resulting in a net force that is not solely directed downwards. As a result, the objects do not accelerate at the full rate of gravity, causing their motion to deviate from true free fall.

Gravity is not unique to the Earth. All matter has gravity and all matter attracts all other matter. Since the Earth has mass it also has a gracvitational field associated with it.
The acceleration of objects in free fall near Earth is approximately 9.8 m/s^2, commonly denoted as "g." This acceleration is due to the force of gravity pulling the objects towards the center of the Earth.
