I have never heard about a plan of cosmic objects endangering Earth to be directed towards the Sun in order to get rid of them. It is unfeasable ? "Sun wind" blowing from the star is stronger than its gravitation ?
As mfb has noted the change in delta V, the velocity of the asteroid or comet, necessary to have it hit the sun is considerable and certainly much more (by perhaps two orders of magnitude or more) than the gentle nudge required to deflect it from an impact with the Earth.Yuri B. said:I meant asteroids endangering the Earth against which many sorts of weaponry are discussed (and probably designed and build).

Yes, it is possible to direct dangerous objects towards the Sun. However, it requires careful planning and precise calculations to ensure the object's trajectory is accurate.
The main risk is the possibility of the object exploding or breaking apart during the journey. This could result in debris entering Earth's atmosphere and causing harm. Additionally, there may be ethical concerns about intentionally sending dangerous objects towards the Sun.
Scientists use complex mathematical equations and computer simulations to calculate the object's trajectory and ensure it will reach the Sun. They also take into account factors such as gravitational pull, resistance from solar wind, and the object's own propulsion systems.
Any object that is able to withstand the extreme temperatures and conditions of space can potentially be directed towards the Sun. This includes large space debris, defunct satellites, and even spacecraft that have completed their missions.
Directing dangerous objects to the Sun can help prevent potential collisions with Earth or other celestial bodies. It also allows for the safe disposal of space debris and defunct spacecraft. Additionally, studying the effects of the extreme environment near the Sun can provide valuable insights for future space missions.
