One the size of a grain of sand.
depending on the size it could destroy the planet or impact in the water and not do much. It all depends on the size of said asteroid!
determining its mass from its gravitational pull on a spacecraft, satellite, or planet.
Missiles can be used to potentially deflect or break up an asteroid, rather than destroy it completely. The effectiveness of this method would depend on the size and composition of the asteroid. Efforts to develop technology for asteroid deflection are currently being researched.
No, an asteroid cannot destroy earth, but a large enough asteroid can have devastating effects on the life on Earth
Asteroid
Venus does not have a natural satellite, though the asteroid 2002 VE68 presently maintains a quasi-orbital relationship with it.
No.
Moon, asteroid, planetoid...
No. The moon is large enough that even a collision with the solar system's largest asteroid would not destroy it.
Destroying an asteroid is a complex and challenging task that would require careful planning and precise execution. Several potential methods for asteroid deflection or destruction have been proposed, including using nuclear explosives, kinetic impactors, or gravitational tractors. The difficulty of destroying an asteroid would depend on its size, composition, and trajectory.
It is a natural satellite.
Depends on its size at time of collision,the heat and vibration can destroy city country or whole world.
