Objects are hitting us every day of every minute.

Some objects in outer space that can damage the earth could be the following: Asteroids Sun Particles Rocks from other planets Space bombs Fire Other objects flying around in space


Huston, we haven't been hit by space objects. I repeat, we have not been hit by space objects, YEAH!


Yes, the whole Earth is always, and will always be impacted by objects from space.


If things from space enter the earths athmospere at a wrong angle they either burn up or thrown back into space .Mainly as the moon has no atmosphere.


Gravity causes them to hit the Earth.


Meteors hit the earth frequently. Shooting stars are space debris that burns up in the atmosphere, but small pieces often make it through.


Various kinds of space rocks will hit the Earth's atmosphere at incredible speed and are frequently incinerated. These are called meteors. If a meteor survives to hit the ground, it is a meteorite.


The Moon is pelted with small space rocks just as the Earth is, with a couple of exceptions. 1. The Moon is a lot smaller than the Earth, so it is hit less often. 2. The Moon is less massive and its gravity is lower, so the space rocks aren't moving as fast when they hit the Moon as they are when they hit the Earth. 2. The Moon has no atmosphere, so there are no meteors on the Moon; however, we do see the explosions as the Moon is hit by the falling space rocks.


Other than the craters, and the fact that we've seen things fall from the sky and then found the remnants of the objects? Chemical analysis of meteorites sometimes reveals that the proportion of elements within the meteorite doesn't match materials found on Earth.


It was obviously nowhere near where I live because I did not even know about it! Nowadays, in a typical year, the earth is hit by approx 15000 tonnes of meteoroids, micrometeoroids and other objects from space.


Small meteorites hit Earth everyday, but large meteorites hit once a year.


Yes because large asteroids heading for earth are Near Earth Objects and if they were to hit many people can lose their lives.


We can only see light from what it's reflected off (planets, objects, the moon, things on Earth), or directly emitted from, such as stars including our sun. Space is a vacuum, and therefore is literally just space, so that space can't be hit by light, and can't reflect it.


Other space junk objects could hit them



It depends on what you call large. Meteorites fall all the time; meteoroids land very often.


Actual collisions are pretty rare. Most 'space debris' burns up in the atmosphere long before it hits the planet.


Yes. A meteorite is a piece of rock or metal from space that has hit Earth's surface.


Uhh, they do, from 65 million years and a lot of them hit in 4.8 billion years as they form the building blocks of life. there may be a 5% or 10% chance of there being another object hitting it in the current time.


Fortunately not very often - because if one does hit, it would be a major catastrophe.


It's not. In fact, the converse is true; the Earth is both a bigger target and has a stronger gravitational field. However, the Earth has a significant atmosphere, and thus weathering, so craters on the Moon tend to last much, much longer than craters on the Earth. The fact that Earth is geologically active and has life also shorten the length of time that craters remain visible and recognizable.


On Earth, this would be impossible because of friction. Moving objects hit air particles and start to slow down. In space however, there is no air. It is a complete vacuum. So, free from friction, moving objects keep their speed.


Even though the planet Earth is very large in comparison to the people who live on it, it is very small in comparison to outer space. It is effectively a small target for comets to hit. And even though the gravitational attraction of the Earth does tend to pull objects such as comets toward it, in most cases the comet (or other object) will still miss, and will then fly past the Earth.


yes, earth may occaisionally be hit by space debris but it usually will burn up in the atmosphere before it hits our planet.


The mesosphere layer protects us from being hit by objects falling from space, like meteoroids. These objects burn up in this layer.
