Defense method of Asteroid Impacts.

Asteroids are objects that are formed from the the remains of dust  when a star is formed, sometimes they can be massive, tiny, large, extra large, their surfaces are rocky and gassed,  Rocky have energy and most of them are made of lava, and also hot temperatures and they are known to escape orbit at full velocity and then so also travel up to vast cosmic distances and then reach up the solar system that they need.

• Since the formation of the sun, an belt ranging from Mars to Jupiters Stratosperic layer, its fiiled with xray radiation and also asteroids kept inside a gravitational field of Jupiters and also rapdily increasing per second when the Moons are orbiting the belt and some of them crushing down On the surface and the gravitational orbiting pull is increased and improved so that they cannot escape the Jupiter, planet orbital speed, for fullest velocity.
• Accorditng to NASA, There are many asteroids within the belt of the sun and some of them are also located near the Earth, these objects are called NEOs(Near Earth Asteroid), These objects are located above 20-31 million Km away from our planets orbit, and we have the following influence on these objects

1. Tracking Them
2. Observing them
3. Lauicnhing a probe to land
4. Gravitational spacecraft to miss the Earth.

So Far, There are no threats of asteroids to kill Earths present civilization, but we have already ruled out scientifiic and physical scenaries of these events.

Some of the best ways would be for that we have tried off  to use such gravitational spacecraft and once the spacecraft has approached the Earth within just 10 million away, to launch it and lower its TNT Impact zone or just change its orbital path to miss the Earth, at fullest velocity.
