Please help me what are they what are their differences and what are they made of?

As far as I understand, comets are bright, hot space dust that travels through space at high speeds.
Asteroids are rocks in our solar system that seperate the inner planets (mercury, venus, earth, mars) from the outer planets (jupiter and beyond)
Meteorites are asteroids that are being pulled away from the asteroid belt.
But, I'm not an astronomer ;-)

Hi. The difference is what they are made of and their size. Comets tend to come from deep space and have lots of ice in them, asteroids are from relatively near space and are mostly rock and metal. Meteoroids can come from either and are small.

Comets - large icy objects in elongated orbits around the sun that evaporate when they get close to the sun and leave a long cloudy trail in the sky for months (visible from earth at night). Can be seen in telescopes in advance so people are aware they will be visible
Asteroids - large rocky objects that are in fairly stable orbits around the sun (most between Mars and Jupiter) - kind of like thousands of little tiny planets instead of one big one. Tens of thousands of asteroids are currently known, and estimates of the total number range in the millions.
Meteroids - when small objects (rock, ice, mixtures) enter the earth's atmosphere they burn up from the friction with the air, and create bright streaks in the sky (visible from very limited locations for just a few seconds)

A comet is a moving object made up of ice, dust and other particals. Astroids are large objects made of metals, mostly iron ore and rock. meteoroids are smaller parts of asteroids that enter an atmosphere such as earths (well they can be very big too).

comets are big chunks of ice, asteroids and meteroids are the same thing I think, except meteriods hit the earth, asteroids don't

no longer some thing loses mass interior the experience that any mass is lengthy previous. Mass is switched over into different varieties as a results of friction and actual forces. even with area of a meteor survives the combustion of air friction may then be at risk of damage-up forces from an impact with the floor. at the same time as it may no longer lose mass, it probable will damage aside to a pair degree.

chunks of ie or rock
