whats the difference between asteroids, metiors, and comets?

Answer 1

Asteroids are rocks in space. Meteoroids are rocks from space that have entered our atmosphere. They are called meteors as they fly through the atmosphere, then called meteorites if they land on the ground. Comets are snowy balls of dirt in space.

Answer 2

asteroids:
a body smaller than a planet and made of rock, metal, or other minerals. there is a large belt of asteroids between Mars & Jupiter

2nd I think u wrote about METEOR:
It is also called as shooting star. a chunk of rock or metal that enter's earth's atmosphere and burns up in a fiery show
meteoroid:
a cunck of rock or metal moving through space.

comets:
an object composed of frozen gases and dust particles that was formed on the outskirts of the solar system and that orbits the sun. most comets have long, skinny orbits that take them beyond the planets.

Answer 3

"asteroid" = looks like a star (in 19th century telescopes, planets showed a disk while minor planets did not, they looked like points of light, just like stars). The word is now reserved for minor planets that are inside Neptune's orbit (the outer ones are called Trans-Neptunian Objects)

"meteor" = phenomena of the atmosphere (From the Greek "meteora" = very high thing). The science that studies the atmosphere is meteorology and, in that science, a cloud is a meteor. In astronomy, a rock that becomes visible as its streaks into the atmosphere is a meteor; if it makes it to the ground, it becomes a meteorite; the antecedent is a meteoroid (the piece of rock in orbit, before it hits our atmosphere).

comet is from the Greek "kometes" = hairy. A star with hair. It is an icy object which liberates gases and dust as it approaches the Sun. Because of light pressure and magnetic field, the escaping gas and dust form a tail (or two) which appear to float behind the head.
