What else can I help you with?
Are asteroids and comets rocks?
Asteroids are composed mainly of rock, metal, or a mixture of the two. Comets are a mixture of ice and rock.
What two space objects produce meteorites?
Asteroids and comets are the two space objects that produce meteorites when they enter Earth's atmosphere and survive the descent to reach the surface. Asteroids are rocky objects that orbit the Sun, while comets are composed of ice, dust, and rock.
What two comets did Clyde tombaugh discover?
Tombaugh was credited with discovering hundreds of asteroids, as well as Pluto in 1930, but no comets.
Name two objects in the solar system besides moons and planets?
Asteroids and comets are two examples of objects in the solar system besides moons and planets. Asteroids are rocky objects that orbit the Sun, mostly found in the asteroid belt between Mars and Jupiter. Comets are icy bodies that also orbit the Sun, with tails that form when they come close to the Sun.
Explain at least two ways that comets and asteroids can affect earth?
it can destroy earth
Where did meteoroids originate?
Meteoroids primarily originate from two sources: asteroids and comets. Most meteoroids are fragments of asteroids, particularly from the asteroid belt located between Mars and Jupiter. Comets, when they approach the Sun, shed debris that can also become meteoroids. Additionally, some meteoroids can originate from the Moon or Mars, where impacts have ejected material into space.
What are the two main features of the moon?
It reflects light from the Sun and it has different phases.
HOW DO ASTEROIDS AND COMETS DIFFERS?
A comet is a large chunk of ice and rock (sometimes you can find iron there, too) with a large tail of ice. Comets are usually relatively small, and some can be formed from a collision between two asteroids. Comets, if they come in contact with Earth, usually are melted to pebbles from the atmosphere. Asteroids, on the other hand, differ greatly in size. They can be as small as a pebble or as big as a city. They are what astronomers and scientists worry about the most. After all, a large enough asteroid destroyed the dinosaurs. Asteroids have no tail of ice, and have no ice at all. They're made of solid rock and iron. Asteroids and comets have many things in common. They're considered space debris from collisions. They smash into planets and cause impacts. They both are made or rock - and sometimes iron - and dance around through deep space doing nothing at all.
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.
In between what two planets are asteroids?
The vast majority of asteroids is in the the asteroid belt between the orbits of Mars and Jupiter. However, there are asteroids all around the solar system.
What are the names of the two other large asteroids?
The two other large asteroids in our solar system are Vesta and Pallas. Vesta is the second most massive asteroid and is located in the asteroid belt, while Pallas is the third most massive and is also part of the asteroid belt between Mars and Jupiter.
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.
