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.

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.”
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.
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.
Asteroids, comets, and meteors are chunks of rock, ice, and metal left over from the formation of our solar system about 4.6 billion years ago.
22 gru 2022 · Scientists have identified three main categories of meteorites: iron meteorites, stony-iron meteorites, and stony meteorites. These categories are distinguished by their structure, chemistry, and mineral content. But that’s not all – each category also has its own subtypes, which adds even more diversity to the world of meteorites.
Our solar system’s small bodies – asteroids, comets, and meteors – pack big surprises. These chunks of rock, ice, and metal are leftovers from the formation of our solar system 4.6 billion years ago. They are a lot like a fossil record of our early solar system.
