yes because if it lands on earth then it could block the sun and crops we have would not grow if it hits hard eough.
asteroids are a threat to us
No, that would be apollo asteroids
No, they all have a very stable orbit.
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
Yes. An asteroid of sufficient size has the potential to wipe out a good percentage of the Earths population. Identifying those asteroids in advance enables us to determine their potential threat and thus enabling us to intercept them before they impact on Earth.
Meteorites help us understand the composition of asteroids because meteorites are small asteroids.
· Apollo spacecraft (US) · asteroids · atmosphere
None, in fact US seems be threat to the world.
yes they are they will let of that mutch dust it will block out the sun if they crash in to us
Us humans are a threat to Bengal tigers
no
Asteroids & meteors are celestial bodies which could'nt make into a planet.there sizes ranges from about yard to about a football field & they travel at great speeds.and when they come into contact to earth this whole of kinetic energy is converted into a huge amount of energy which could be eqivalent to some tonnes of TNT & could destroy life on earth. hence,these always pose a threat to mass extinction.
