How big does a meteor have to be in order to hit Earth?
Meteors that hit Earth can vary in size, but typically need to be at least 25 meters in diameter to survive the journey through the atmosphere and make an impact on the surface.
'when a ball fall on earth the earth also moves up to meet it but motion of earth is not notable why'?
Ball pulls the Earth with force of the same value as the force that Earth pulls the apple with, according to Newton's laws of motion. However, mass of Earth is quite a couple orders of magnitude higher than the mass of ball, and the force of pull moves ball more easily than Earth. Also, you can't observe the Earth's movement in this case in a frame of reference fixed to Earth, as you're moving with it - that is your relative speed relative to Earth is zero and vice versa. You would need an observation point unrelated to Earth.
What is the force you need to use in order to lift a mass of 40kilogram?
-- If the 40 kilogram mass is on the Earth, you need about 392 newtons (88.2 pounds).-- If the same mass is on the moon, you need about 64.9 newtons (14.6 pounds).-- If it's inside a space ship with you and your ship is coasting, then you canlift it with ANY force, no matter how large or small. In fact, after you lift it, you'llneed to apply force in the opposite direction in order to make it stop lifting.

Quantifiable Performance Measures
How many kilograms are in 1 billion pounds?
348,169,930 ======================== Another contributor intervened: Sorry. 348,169,930 kilograms weigh only 767,582,391.1 pounds on earth ... about 23.2 percent short of 1 billion pounds. In order to make 1 billion pounds of weight, on earth, you need 453,592,909.4 kilograms of mass. In order to do it on the moon, you need 2,778,256,570 kilograms, or about 6.1 times as many as on earth.
If an asteroid impact were to stop the Earth from rotating how big would that asteroid need to be?
size doesn't matter its the angle and speed of the asteroid that it is at, plus if that did happen the earth would either drift off into space and eventually get back into a orbit because of the suns gravity or explodes and everything would just flip, roll over, fall how ever you wanna put it. plus its nearly impossible for a asteroid to do that it would probably do what i said in the second sentence.
Why should we care about the asteroid belt?
Because the asteroid belt is apart of the universe and without it we wouldn't have oxygen on Earth. Of course, if we didn't have oxygen on Earth we would all die. So therefore we need it!
Do you need to aim for the asteroid?
Yes. To destroy asteroids and protect the earth you must aim for the asteroids with nukes or the laser beam house.
How much damage would a 50 meter asteroid cause upon impact?
A 50 meter asteroid could cause significant damage upon impact, potentially creating a crater and causing widespread destruction in the surrounding area. The exact extent of the damage would depend on various factors such as the composition of the asteroid and the location of impact.
How big does a meteor have to be in order to hit Earth?
Meteors that hit Earth can vary in size, but typically need to be at least 25 meters in diameter to survive the journey through the atmosphere and make an impact on the surface.
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.
If an asteroid passed by Earth at just the right distance it would be captured by Earth's gravity and become our second moon?
It is highly unlikely for an asteroid to become a second moon of the Earth. For an object to be captured as a moon, it would need to slow down significantly to match Earth's velocity, which is a rare occurrence in space due to various factors like velocity, trajectory, and gravity. Even if an asteroid did get captured, it might not stay in a stable orbit and could eventually be flung back into space or collide with Earth.
How massive would a body need to be to effect the earth?
A body of ANY mass will affect the earth. You may not be able to measure the impact of something very small, but it still has an impact.
How does the gravitational force of an asteroid flying close to Earth affect our planet?
When an asteroid flies close to Earth, its gravitational force can potentially cause small changes in the Earth's orbit and rotation. However, these effects are usually minimal and do not pose a significant threat to the planet.
If you were on Jupiter could you see the asteroid belt?
The main asteroid belt is about 1.7 AU from Earth, whereas from Jupiter it would be about 3.3 AU. From Earth, only the largest asteroids are visible and that's with very good telescopes. So you'd need even better telescopes to see it from Jupiter.
How to calculate if an asteroid will hit the earth?
There is essentially no chance of any given asteroid ever hitting the Earth, because those with orbits that made them likely to hit the Earth have already hit the Earth. So it's not something you really need to worry about.If you're just curious... well, really, you don't want to know that badly. It comes down to solving n-body gravitational equations, and for any reasonably sized n (i.e. larger than, say, 3) there is no known exact solution except in special cases, so you have to use numerical methods and hope the interesting bits don't get lost in rounding errors.
How high do you need to be in order to see the curvature of the Earth?
In order to see the curvature of the Earth, you would need to be at an altitude of at least 35,000 feet, which is the cruising altitude of commercial airplanes.
