Are comets or asteroids more dangerous?
While asteroids and comets have different constitutions - asteroids are mostly metals and rocks while comets consist of water-ice, dust and rock - with comets potentially being potentially less dense, comets travel much faster than asteroids. An asteroid may travel upwards of 40,000 miles per hour, a comet travels over 150,000 miles per hour.
Explain at least two ways that comets and asteroids can affect the Earth?
Comets can affect Earth in the future and have affected Earth a great deal in the past. Primordial Earth: Primordial Earth, particularly in the first billion years of Earth, was shaped greatly by comets and asteroids and meteorites. Based on the known populations of comets now and projections to that earlier time, there is substantial evidence that half or more of all water on Earth was brought by comets. Comet History: Comets were a pretty unexpected apparition in the night sky before anyone knew what they were. For thousands of years people have seen them an taken them to be some kind of omen. History records great events and decisions connected with comets. Starting around the 1600s when science and astronomy were becoming separate from astrology and magic, comets were a helpful and motivating factor in stimulating the study of the cosmos. They have been such ever since. We now know that comets are the source of meteor showers, an amazement to mankind throughout history. There are not many reliable examples of large comets striking the Earth in recent history, but we can be quite certain that is has happened. Comet Shoemaker-Levi was quite spectacular when it hit Jupiter in 1993, leaving a disturbance in Jupiter's atmosphere that was larger than the size of the Earth. Comet Future: Still a a stimulus for scientific study, comets give us an opportunity to sample material from the most distant parts of the solar system. In particular, the source of most comets is from either the Kuiper belt beyond Neptune or the far more distant Oort cloud. Comets are large enough to be dangerous. Comet nuclei range from about 100 meters to tens of kilometers across. They are not solid like asteroids but composed of rock, dust, water ice, and frozen gases. Still, a large comet impact on Earth could be catastrophic for life and probably has been in the distant past. Unlike asteroids, they are less likely to appear suddenly and the probabilities for such a disaster are much lower for comets than asteroids.
What actions promote a more scientific understanding of comets asteroids and meteors?
Actions we could take to promote a more scientific understanding of comets, asteroids, and meteors would start with education. Educate more in schools, colleges, television, and movies.
Are asteroids cooler than comets?
In terms of "cool" (as in "awesome"), this question is entirely opinion. I think most people would consider comets more awesome than asteroids because comets are sometimes visible from earth. In terms of temperature, comets are made mostly of rock and ice. However, when their orbits are close to the sun, they can heat up and burn off some of the ice, forming the comet's tail. This means that a comet's temperature can vary depending on where it is in its orbit. On the other hand, asteroids in the asteroid belt have fairly regular orbits, which means that their temperature is fairly constant: cold.
Which object in the solar system is a frozen mass of ice or dust?
i believe that the answer to that aught to be either comet or asteroid
Does comets have to do with the water on earth?
We think no the isotopic makeup of cometary water would not seem to match that found in the oceans. Latest thinking is that Earth's water may have been delivered from the asteroid belt (by asteroids rather than comets). However, please note that there is no final consensus on this yet and other people postulate that Earth's water was there form the start and not delivered later. Whichever way, Earth got its water early on.
What are some Interplanetary objects?
The number one thing in our solar system is space, or empty vacuum, through which blows the solar wind. The sun is the next largest thing in the solar system, outmassing all the planets, asteroids, comets, and icy debris beyond the orbit of Neptune by a factor of a thousand.Planets, their moons, the Kuiper Belt, Oort Cloud, comets, asteroids, and meteroids constitute much of the remainder of the solar system.Our solar system consists primarily of the sun, which accounts for 99% of the solar system's total mass. The remaining 1% are the eight major planets and their moons, numerous minor planets, and other bodies such as comets and asteroids.
When did asteroids hit Jupiter?
The Minor Planet center has cataloged 279,722 minor planets which are asteroids, comets, and dwarf planets. Considering asteroids and comets are in some ways related bodies in the fact that they do not have hydrostatic equilibrium; we only have to subtract the four dwarf planets leaving us with 279,718 asteroids and comets discovered so far.
Do asteroids have tails?
It's assumed those asteroids that once were comets have had the ice and dust burned off and now have nothing coming off to make a tail.
What is the brightest objects in the universe?
That would include: Sun Mercury Venus Earth Mars and its moons Jupiter and its moons Saturn and its moons Neptune and its moons Uranus and its moons Pluto and other planetesimals and their moons Asteroids Comets
What would you hear on Saturn?
Nothing. Sound can not travel in space due no air.I have no clue why the previous person who answered thought you can hear asteroids and comets.
Which is the most likely to Make a more frequent “visitor” of earth. Why do you think so?
I believe that the most probable thing that a visitor to the Earth would do would be to study the living beings that inhabit it and measure their level of intelligence and what type of organisms they are or how it is possible that they exist. Now why I think this is what they would do … easily because if humans found a planet with living swerves is not the first thing we would do
