What else can I help you with?
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.
Do asteroids come close to the earth?
They can.
What comet or asteroid will come close to the Earth in 2012?
Comets are difficult to predict; we currently know of no comets that will be visible in 2012, but new ones are discovered periodically. No asteroids that we are aware of will approach the Earth very closely before April 13, 2029, when the asteroid Apophis will come fairly close the Earth. (But it will miss.)
When is an aseriod next predicted to hit the earth?
There are currently no known asteroids predicted to hit the Earth in the near future. Scientists continuously monitor asteroids and comets that come close to Earth, and there are no imminent threats at this time.
What do meteroids come from?
comets of asteroids .
What causes asteroids meteoroids and comets to orbit the sun?
Asteroids, meteoroids, and comets orbit the Sun due to the gravitational pull between these celestial bodies and the Sun. Their orbits are influenced by their initial velocity, mass, and distance from the Sun. When they come close to Earth, they can be observed as shooting stars or meteor showers.
Has a rogue planet ever come near earth?
As far as we know, no rogue planet has ever come near Earth. Comets and asteroids have come near Earth, but not actual planets.
Compare and contrast asteroids and comets?
Both asteroids and comets are celestial bodies in space, but they differ in composition and appearance. Asteroids are mainly made of metal and rock, and are found mostly in the asteroid belt between Mars and Jupiter. Comets, on the other hand, are made of ice, dust, and rock, and come from the outer regions of the solar system. Comets also have a tail that forms when they get close to the Sun, while asteroids do not.
How close do comet to the earth?
Comets have their own orbits in our solar system around the sun. They don't come close to the earth.
Why have comets happened?
Comets are solid pieces of rock that are in long elliptical orbit around the sun. They occur because pieces of other space objects (asteroids, moons, planets, etc.) were knocked off into this path, and the path just happens to come close to the Earth.
What are NEAs?
Most asteroids are in the Asteroid Belt between Mars and Jupiter. But a few do come close to the Earth; these are called Near Earth Asteroids. You can see a list of NEAs, and the dates that they will come closest to the Earth, at www.spaceweather.com. Asteroids and comets have collided with the Earth in the past, and someday one will collide with Earth in the future. Depending on the mass of the asteroid, the damage could be catastrophic. 65 million years ago, scientists now believe that an asteroid or comet hit the Earth, causing the extinction of the dinosaurs and most life on Earth.
What are comets asteroids and meteoroids?
Asteroids comets and meteoroids all are masses of land sometimes inflamed and usually come from parts of planets hurtling through space.
