What is asteroid impact prediction?
Q: What is asteroid impact prediction?
A: Asteroid impact prediction is a way of warning about asteroids that may hit Earth, and when and where they will hit the Earth.
Q: How does asteroid impact prediction work?
A: Asteroid impact prediction works by finding asteroids that might hit Earth in the future. It looks for big asteroids as they can be seen easily from a long distance, many years before they come close to Earth. For smaller space rocks, telescopes are used to find them but it's not always possible to see them until they are close to Earth.
Q: How many big asteroids are there?
A: There aren't many big asteroids, but there are millions of smaller space rocks.
Q: How do we find small asteroids?
A: We use telescopes to find the small asteroids that are going to hit Earth soon, although it's not always possible to see them before they get too close.
Q: Are all asteroids visible from a long distance?
A: No, most asteroids will not be visible from a long distance as they are usually too small or faint for us to detect until they get closer to Earth.
Q: Can we predict when an asteroid will hit earth accurately?
A: Not always - because of the difficulty in detecting small asteroids until they get close enough, it can be difficult or impossible to predict exactly when an asteroid will hit earth with any accuracy.
Q: Is it possible for us to stop an incoming asteroid from hitting earth? A: In some cases yes - if we have enough time and resources available then it may be possible for us to divert or destroy an incoming asteroid before it hits earth.
