Differences between Asteroid, Meteor and a Comet

A comet is a relatively small solar system body that orbits the Sun. When close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail.

An astroid is a relatively small, inactive body, composed of rock, carbon or metal, which is orbiting the Sun.

A meteoroid is a piece of interplanetary matter that is smaller than a kilometer and frequently only millimeters in size. Most meteoroids that enter the Earth’s atmosphere are so small that they vaporize completely and never reach the planet’s surface.

What's the difference between an astroid, meteor and a comet?

Facts- A meteoroid that burns up as it passes through the Earth’s atmosphere is known as a meteor. If you’ve ever looked up at the sky at night and seen a streak of light or ‘shooting star’ what you are actually seeing is a meteor.A meteoroid that survives falling through the Earth’s atmosphere and colliding with the Earth’s surface is known as a meteorite.The fastest meteoroids travel through the solar system at a speed of around 42 kilometres per second (26 miles per second).The Earth’s atmosphere experiences millions of meteors every day.Meteors are easier to see during the lower light conditions of night.A small percentage of meteoroids fly on a path that goes into the Earth’s atmosphere and then back out again, they are known as Earth grazing fireballs.When many meteors occur in a close time frame in the same part of the sky it is called a meteor shower
