Solar Empire Impact!?
Question:
how can you make sure that a stone that float near our earth can be categorized as a meteorite?
why comet is more danger than asteroids?
what will happen if a big meteorite hit our earth?
what is the difference between asteroids and comets?
Answer:
why do some asteroids become a danger material to the earth?
Some asteroids' orbits cross earth's orbit. This means that they may be a threat to earth in the future. There are many near earth asteroids that have been found, and some are forecasted to make very close passes. They could potentially hit earth.
how can you make sure that a stone that float near our earth can be categorized as a meteorite?
A meteorite is the name of the rock after it has hit earth. That's what's left. So if it will be categorized as a meteorite, it must have hit the earth.
why comet is more danger than asteroids?
It depends on the size, actually. Small comets aren't as dangerous as large asteroids. Comet vs asteroid doesn't really matter, but comets may be moving faster than an asteroid, especially if it is a long period comet. It will be travelling much faster than a near earth asteroid.
what will happen if a big meteorite hit our earth?
I think you mean meteor. A meteorite is the rock after it has hit earth. But if a big meteor hits earth, it will cause a large amount of damage at the site of impact, including a crater. The ground will be superheated and many fires will start. The ejecta (hot rock ejected from the impact site) will land in the surrounding area and cause damage, including fire. The dust and debris from the impact will go into the atmosphere and spread around the world, resulting in a dark and cold period that lasts several months. Many animal and plant species will go extinct in this time.
what is the difference between asteroids and comets?
Asteroids are composed largely of rocks (silicates) and metal (iron), while comets are composed mainly of ice and some rock. Comets will get a long tail of debris as they near the sun, as the ice sublimates.
Most asteroids are a couple hundred miilion miles away, between Mars and Jupiter. But some renegades come close to Earth, probably as a result of an accidental gravitational interchange with another asteroid.
Any rock in space less than one kilometer across is properly called a meteor. Larger than that is an asteroid.
Comets are not necessarily more dangerous. In fact many asteroids are larger than comets, and being made of iron and nickel, impacting us would do a lot more damage.
The amount of damage from a meteor impact depends on where it lands. In the middle of the Sahara Desert, you have abig hole in the desert. Drop one on a city and you have a lot of dead people.
Comets are basically dirty snowballs--frozen water, carbon dioxide, ammonia, plus grit, gravel and general dirt. Asteroids are large rocks, some with iron and nickel in them.
1) Asteroids become dangerous to the Earth when they make close approaches to our planet. Some asteroids, known as near-earth asteroids, have orbits that always cross ours, but seldom make close encounters. When however these do make close approaches, there is always the possibility of being hit by one. Though our atmosphere offers a first line of defense, if an asteroid even 1 mile across entered the sky, it would create a massive explosion. Some near Earth asteroids are more than 30 miles across. An impact like this would effectively end life as we know it.
2) A meteorite is the term used for describing a meteor once it has hit the ground, while a meteor is the term used for a meteoroid that has entered the astmosphere. Meteoroids are small particles that have broken off comets and asteroids and run into Earth's orbit. They don't usually orbit our planet, we just run into them as we speed along around the sun.
3) Truthfully, a comet is not more dangerous than an asteroid. The reason for this is simple...Though comets have a gaseous tail, and some water ice, they are MUCH smaller than most asteroids, so the resulting impact on Earth, though deadly, would be better than that of a larger asteroid.
4) If a large meteor hit the Earth, it would make a loud explosion, destroy many trees, (or buildings, depending on where it hit), and if it was large enough, wipe out everything for hundreds of miles. If a very large one hit the ocean, it would cause incredibly dangerous tsunamis, that would flood many cities. Also a layer of dust would rise into the air, blocking the suns rays, chilling our planet, and leading to another ice age.byebye humans.
5) Asteroids are rocks that orbit the sun, they can be from one mile across or smaller, to hundreds of miles across. They usually glow dimly in the sky because their surface is covered in dust.
Comets are icy balls of rock, that orbit the sun in a huge parabolic orbit. When they are near the sun, the gas trapped in their nucleus is released itno a majestic tail. They are smaller than asteroids and only appear brighter when they are near the sun and a tail is created.
