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 else can I help you with?
Which of these hit the earth comets or asteroids?
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
How can comets and asteroids affect earth?
Comets and asteroids can potentially impact Earth, causing damage due to the energy released upon impact. They can also bring valuable resources to our planet, such as water and metals. Additionally, dust and gas released by comets passing close to Earth can affect our atmosphere and climate.
What sites will you see on the way from Earth to Uranus?
asteroids and comets!
All meteorites collected on Earth come from asteroids or comets?
Most meteorites come from asteroids, which are rocky bodies orbiting the sun. Some meteorites could also come from comets, which are icy bodies. Both asteroids and comets can collide with Earth, resulting in meteorites.
What do comets and asteroids have in common?
Comets and asteroids are both celestial bodies orbiting the Sun. Comets are icy bodies that develop a tail when passing close to the Sun, while asteroids are rocky or metallic objects that typically orbit in the asteroid belt between Mars and Jupiter. Both comets and asteroids can occasionally enter Earth's vicinity.
Explain at least two ways that comets and asteroids can affect earth?
it can destroy earth

What is the name of comets after they land on earth?
asteroids
Do comets or asteroids come close to earth?
Yes

Are comets asteroids meteors and dwarf planets on earth?
No. They are in space.

What are facts about comets and asteroids?
Comets are icy bodies that originate in the outer regions of the solar system and develop tails when they approach the sun, whereas asteroids are rocky and metallic bodies that orbit the sun mainly in the asteroid belt between Mars and Jupiter. Comets are composed of ice, dust, and rocky material, while asteroids are primarily made of rock and metal. Both comets and asteroids can pose a potential threat to Earth if they collide with our planet.
Celesitial neighbors of earth?
Moon Near-Earth Objects (asteroids, comets) Venus Mars
How do the the orbits of comets and asteroids compare to that of planet Earth?
they go around the sun like the earth
