Which is most likely to make a more frequent visitor of earth a comet or an asteroid?

assteroids


Why would scientists want to know if an asteroid is on a course to collide with earth in 20 years?

If an asteroid were to hit Earth, it could do HUGE damage. It was the changes to Earth after an asteroid hit that killed off the dinosaurs. But if we knew about an asteroid heading our way long enough ahead of time, maybe we could change it's course enough to make it miss, and save millions of lives.


What can make the moon explode?

The most obvious answer is when another object of significant size, such as a stray asteroid, hits the moon.


Which asteroid comes closer to the earth than any other?

The problem with naming a particular asteroid as the one that "comes closer than any other" is that we keep discovering new asteroids flying around that come even CLOSER. At one time, the asteroid "Eros" was the one described as coming closest, but that title may now go to the asteroid Apophis. Apophis will make a very close approach to the Earth on April 13 (Friday the 13th!) 2029, and again on April 13, 2036. The 2029 pass will bring Apophis closer to the Earth than many communications satellites!


How does an asteroid hit a planet?

An asteroid hits a planet when its trajectory brings it into the gravitational field of the planet, causing it to be pulled towards the planet's surface. The impact occurs when the asteroid collides with the planet's atmosphere and surface due to the planet's gravitational pull.

What happend to the earth after an asteroid hit?

After an asteroid impact, the Earth can experience widespread devastation, including massive fires, tsunamis, and a "nuclear winter" effect from debris blocking sunlight. Depending on the size of the asteroid, the impact could lead to mass extinctions and significant changes to the environment. Recovery and rebuilding could take millions of years.


Earth's moon hypothetically was a portion of earth when it was hit by an asteroid how was this possible?

if a meteor hit earth and a piece of earth (the moon) chipped off. earths gravitational pull could be sufficient to make the moon orbit around the earth.


How close does an asteroid have to be to Earth to fall into our planet?

Its not only a question of distance but a question of speed too. The Momentum of the asteroid is the right parameter to calculate before deciding if earth's gravity will pull it away from its trajectory (unless coming directly towards us) and make it plunge towards us.Thus we need these parameters before answering this question: 1-Speed of the asteroid 2-Mass of the asteroid ( momentum = Mass X Speed) (Gravitational force = Mass X g) 3- Direction of the asteroid 4-The least important is the distance from earth. To simplify all, it's not so direct as you think.
