Meteors, and meteorites are often called “shooting stars” - bright lights streaking across the sky. But we call the same objects by different names, depending on where they are located.
Meteor. A meteor is a meteoroid that enters Earth's atmosphere. They can be observed at night time when they can be seen as a streak of light across the sky. They are popularly known as SHOOTING STARS. Earth's atmosphere burns up the meteoroid because the high speed of the object produces immense friction and typically the object is vaporised.
When meteoroids enter Earth’s atmosphere, or that of another planet, at high speed and burn up, they’re called meteors. This is also when we refer to them as “shooting stars.” Sometimes meteors can even appear brighter than Venus – that’s when we call them “fireballs.”
In meteor astronomy, there are five fundamental terms: meteor, meteoroid, and meteorite are the best known, and dust (interplanetary) and meteoric smoke a bit less known, but of equal scientific importance.

1 lis 2012 · Meteors are pieces of space debris that plow into the Earth's atmosphere. Because they arrive at very high speeds — anywhere from 11 to 74 kilometers (7 to 46 miles) per second — they vaporize by air friction in a white-hot streak.
8 sie 2011 · When a meteor makes it through the atmosphere without burning up entirely, the remnants found on earth are called meteorites. Above, a meteor outburst during the Perseid meteor showers of 1995...
